The surface area of a cube is 294 square inches. What is the length of a lateral edge?
Answer:
7 inches
Step-by-step explanation:
The surface area of a cube is denoted by: A = 6s², where s is the side length.
Here, we know that A = 294, so plug this into the formula to solve for s:
A = 6s²
294 = 6s²
s² = 49
s = √49 = 7
Thus, the answer is 7 inches.

How many times more is 2 ^ 10 than 2^ 6
Answer Choices
12
16
8
Answer:
16
Step-by-step explanation:
Evaluate the two in order to compare them.
2^10=2*2*2*2*2*2*2*2*2*2=1024
2^6=2*2*2*2*2*2=64
The question says how many more TIMES. This tells us that we need to see how many times does 64 go into 1024. To do this, divide 1024/64=16
The answer is 16! Hope this helps ^^

What is the circumference of a circle whose radius is 20 feet. Leave awnser in terms of pi
Answer:
40π
Step-by-step explanation:
cricumference: 2πr (or πd)
2π(20) = (40)π ≈ 125.66
Answer: 40
Step-by-step explanation:
First, you have to multiply the radius by 2 which gives us 40. Then, 40 x 3.14 (pi) = 125.6 After, you divide 125.6 by 3.14 which once again gives you 40. :)

Answer:
[tex]\boxed{\sf{4}}}[/tex]
Step-by-step explanation:
Use a slope form.
Slope:
[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
y₂ = (17)
y₁ = (1)
x₂ = (2)
x₁ = (-2)
Then, rewrite the problem.
Solve.
[tex]\sf{\dfrac{17-1}{2-(-2)}=\dfrac{16}{4}=\dfrac{16\div4}{4\div4}=\dfrac{4}{1}=\boxed{\sf{4} }[/tex]
Therefore, the slope is 4, which is our answer.
I hope this helps you! Let me know if my answer is wrong or not.

x2 + x - 12 as (x + p)(x+ 9).
i need answer asapp!!!
will mark brainliest!!!!
For this case we have the following polynomial:
x2 + x - 12
Factoring we have:
(x-3) (x + 4)
We note that the polynomial is written as:
(x + p) (x + q)
Thus,
p = -3
q = 4

Fill in the table using this function rule y=-10x+1
Answer:
11, 1, -9, -49
Step-by-step explanation:
(Fill in the x value for each one then solve)
Function rule: y = -10x + 1
1. x = -1
fill in: y = (-10) -1 + 1
Solve: 11
Table way: x,y = -1,11
2. x = 0
fill in: y = (-10) 0 + 1
Solve: 1
Table way: x,y = 0,1
3. x = 1
fill in: y = (-10) 1 + 1
Solve: -9
Table way: x,y = 1,-9
4. x = 5
fill in: y = (-10) 5 + 1
Solve: -49
Table way: x,y = 5,-49

What is x
Answer:
x = 98 , x = 20.5
Step-by-step explanation:
[tex]\frac{x}{14}[/tex] = 7 ( multiply both sides by 14 to clear the fraction )
x = 98
[tex]\frac{x}{5}[/tex] = 4.1 ( multiply both sides by 5 to clear the fraction )
x = 20.5
Step-by-step explanation:
#1
x/14=7
x=14×7
x=98
#2
x/5=4.1
x=5×4.1
x=20.5
∠A and ∠B are supplementary. The measure of ∠A is 34°.
What is the measure of ∠B?
Enter your answer in the box.
Please help!
Answer:
146
Step-by-step explanation:
Given;
∠A and ∠B are supplementary. The measure of ∠A is 34°.
To Find;
What is the measure of ∠B?
Note:
Supplementary = 180 degree
Solve:
Since supplementary = 180 degree
34 + x = 180
Subtract 34 from both sides
x + 34 - 23 = 180 - 34
Simplify
x = 146
Hence, the measure of ∠B is 146

Which ordered pair is a solution to the following system of inequalities?
y ≤ –x2 + 5x
y > x2 – 4
(–1, –1)
(0, 2)
(2, 5)
(4, 1)
Verifying the conditions, it is found that ordered pair (2,5) is a solution to the given system of inequalities.
What is the system of inequalities?As stated in the problem, it is modeled by:
y ≤ –x2 + 5x
y > x2 – 4
For ordered pair (-1,-1), we have that:
y ≤ –x2 + 5x
-1 ≤ –(-1)2 + 5(-1)
-1 ≤ -6
Which is false.
For ordered pair (0,2), we have that:
y ≤ –x2 + 5x
2 ≤ –(0)2 + 5(0)
2 ≤ 0
Which is false.
For ordered pair (2,5), we have that:
y ≤ –x2 + 5x
5 ≤ –(2)2 + 5(2)
2 ≤ 6
Which is true.
y > x² - 4
5 > 2² - 4
5 > 0
Which is true.
Hence ordered pair (2,5) is a solution to the given system of inequalities.

Fifteen less than the square of a number is the same
as twice the number. Find the number.
Call the number : a
We have : [tex]a^{2} - 15 = 2a[/tex]
[tex]- > a^{2} - 2a = 15 - > a(a-2) = 15[/tex]
Now, we list all the numbers that can be multiplied to get 15 :
1 x 15 (and reverse)
3 x 5 (and reverse)
-1 x (-15) (reverse)
-3 x (-5) (a l s o r e v e r s e)
We substitute in :
If a = 1 -> a(a-2) = 1 x (-1) = -1 (not equal 15)
If a = 3 -> a(a-2) = 3 x 1 = 3 (not equal 15)
If a = -1 -> a(a-2) = -1 x (-3) = -3 (also not equal 15)
And if a = -3 -> a(a-2) = -3 x (-5) = 15 (satisfied)
So, the number is -3
Recheck : -3(squared) - 15 = 9 - 15 = -6
Twice of -3 = -6
[tex]========================================[/tex]
First of all, let the unknown number be z.
Then, "the square of z" means "z squared" which is the same as "z times z" or just z².
Now, "fifteen less than the square of z" means we subtract 15 from z²:
z²-15
Then, this equals twice the number, or 2 times z:
z²-15=2z
