Answer:
[tex]\boxed{4x^{2} - 48x + 144}[/tex]
Step-by-step explanation:
Given expression:
(2x - 12)²To simplify the expression, we will use the formula (a - b)² = a² - 2ab + b².
[Where "a and b" are the first and second term in (a - b)²]
[tex]\rightarrowtail (2x - 12)^{2}[/tex]
In this case, the first term of (2x - 12)² is "2x" and the second term is "12".
[tex]\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\small\text{First term = a = 2x; Second term = b = 12]}[/tex]
Now, simplify the expression.
[tex]\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2}[/tex]
[tex]\rightarrowtail (2x)(2x) - (4x)(12) + (12)(12)[/tex]
[tex]\rightarrowtail \boxed{4x^{2} - 48x + 144}[/tex]

4(x−3)=9
Add 2 to both sides.
Apply the distributive property to get 4x−12=9.
Apply the distributive property to get 4x−3=9.
Subtract 9 from both sides.
Answer:
B. Apply the distributive property to get 4x-12=9[tex]\boxed{\sf{x=\dfrac{21}{4}=5.25 }}[/tex]
Step-by-step explanation:
Isolate the term of x from one side of the equation.
Use the distributive property.
Distributive property:
[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]
4(x-3)=9Expand the form multiply.
4*x=4x
4*3=12
Rewrite the problem down.
4x-12=9
Add by 12 from both sides.
4x-12+12=9+12
Solve.
Add the numbers from left to right.
9+12=21
4x=21
Divide by 4 from both sides.
4x/4=21/4
Solve.
Divide the numbers from left to right.
x=21/4
21/4=5.25
x=21/4=5.25
Therefore, the final answer is x=21/4=5.25.I hope this helps you! Let me know if my answer is wrong or not.
The answer is B. Apply the distributive property to get 4x−12=9. You would do 4 times x to get 4x and then 4x3 to get 12. Then apply that information to the equation to get 4x−12=9.
If each vowel in the word COLLEGE substitutes with the next letter of the English alphabetical series and each constant is substituted with the 2nd letter preceding it. How many vowels are present in the new arrangement? Fast plsssssssssssss with steps....
Answer:
2
Step-by-step explanation:
Following the substitution rules:
O becomes P and
E becomes F
because they are vowels(a,e,i,o,u) change to next letter.
C becomes A
L becomes J
G becomes E
because constants change to the letter two before the given letter.
So COLLEGE becomes APJJFEF
so it now has 2 vowels.
Devaughn is 6 years older than Sydney. The sum of their ages is 80. What is Sydney's age?
Answer:
37 and 43
Step-by-step explanation:
There are some ways to do this, but this is what I like to do. First, since there are 2 people, I divide 80 by 2, which is 40. Now I add 3 to one person and subtract 3 from one person, because the age difference is 6 years, and there are two people (if you divide them you get 3). Now you get the answer; 37 and 43.
The table shows the possible outcomes of spinning the given spinner and tossing a fair coin. find the probability of spinning a 1 and tossing a head.
Considering a six-sided spinner, it is found that the probability of spinning a 1 and tossing a head is of [tex]\frac{1}{12}[/tex].
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the spinner, one is one out of six possible outcomes.For the coin, a head is one out of two possible outcomes.Since the events are independent, the probability of spinning a 1 and tossing a head is given by:

The dimensions of a rectangular garden were 5 m by 12 m. Each dimension was increased by the same amount. The garden then had an area of 120 m2. Find the dimensions of the new garden.
if dimensions were 5 and 12, that means ratio was 5:12. if we increase wach dimension by the same amount, the ratio is the same.
so:
5x×12x=120
60x²=120
x²=120÷60
x²=2
x=√2
that means each dimension was increased by √2
so dimensions are: 5√2 and 12√2
Kevin is remodeling his bathroom. He needs to cut a circular hole out of a countertop to place the sink, as shown in the figure. What will be the area of the countertop once Kevin cuts the hole, to the nearest square inch? Use 3.14 as an approximation for pi.
Answer:
838 inches²
Step-by-step explanation:
Finding the area of the countertop including the hole
⇒ Area of countertop including hole: LB
⇒ Area of countertop including hole: (24)(48)
⇒ Area of countertop including hole: 1152 inches²
Finding the area of the hole (sink)
⇒ Area of hole: πr²
⇒ Area of hole: (π)(D/2)²
⇒ Area of hole: (π)(20/2)²
⇒ Area of hole: (π)(10)²
⇒ Area of hole: (π) x 100
⇒ Area of hole: 3.14 x 100 = 314 inches²
Finding the area excluding the hole
1152 - 314 = Area of countertop (excluding the hole)
838 inches² = Area of countertop (excluding the hole)

g(x) = x^2 + 6
Step-by-step explanation:
We are trying to find what is g(x) from the graph. f(x) = x^2 translated to g(x).
g(x) = (x - h)^2 +k
It appears the graph is just translated up by k = 6 and no transition of left/right h = 0.
g(x) = (x-0)^2 + 6

The proportion equation is A = 6 : 7
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion equation be represented as A
Now , the value of A is
The height of Maisa is P = 1.5 m
The value of 1.5 m = 150 cm
And , the height of Arman = 175 cm
So , the proportion is
A = height of Maisa / height of Arman
Substituting the values in the equation , we get
A = 150 / 175
A = 6/7
Therefore , the value of A is 6 : 7
Hence , the proportion is 6 : 7

Find the slope of the line that is parallel and perpendicular to the following equation.
2x - y = 1
Answer:
Slope of the line that is parallel: 2
Slope of the line that is perpendicular: [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
For the parallel line:
Rewrite your equation to slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)2x - y = 1 <== subtract 2x to both sides
-2x -2x
-y = -2x + 1 <== divide both sides by -1
/-1 /-1
y = 2x - 1
The slope of the line that is parallel to this line is 2.
For the perpendicular line:
*Perpendicular lines have negative reciprocals*
Steps:
1. Take your original slope (2)
2. Flip it (1/2)
3. Change the sign (-1/2)
For a slope of 2, the reciprocal would be: [tex]-\frac{1}{2}[/tex]
Hope this helps!
Note that.
Slopes of parallel line are equal
Slopes of perpendicular lines are negative reciprocals
So
2x-y=1y=2x-1Compare to slope intercept form

Slope of the perpendicular line=-1/2

Step-by-step explanation:
Hello!
Betty is 5 more than 3 times Jadyn's age. Since Jadyn's age is unknown, we'll call that unknown variable x.
Betty is 5 more than 3 times x. Betty is also 41 years old.
Equation: 41 = 3x + 5
Now we have to solve for x
Solve for x:
41 = 3x + 536 = 3xx = 12
