A rectangle has a width of (3x² – 5x – 2) units and a length of (2x² + 12x - 4) units. Create a simplified expression of the form ax+ bx + c for the perimeter of the rectangle.
Perimeter = ........... units
Answer:
b=(3x² – 5x – 2)
l=(2x² + 12x - 4)
perimeter= 2(l+b)
=2( 2x² + 12x - 4+3x² – 5x – 2)
=2(5x²+7x-6)
=(10x²+14x-12) units

Solve for w: -4u-w = u+6w
Answer:
w = -(5 u)/7
Step-by-step explanation:
Solve for w:
-w - 4 u = 6 w + u
Hint: | Isolate w to the left-hand side.
Subtract 6 w - 4 u from both sides:
-7 w = 5 u
Hint: | Solve for w.
Divide both sides by -7:
Answer: w = -(5 u)/7
Solve 2(4x+2)=4x-12(x-1)
Answer:
x = 1/2
Step-by-step explanation:
Answer:
x = 0.5
Step-by-step explanation:
2(4x+2)=4x-12(x-1) (by PEDMAS, we deal with the parentheses first by using the distributive property)
4x(2)+2(2)=4x+ x(-12) -1 (-12)
8x + 4 = 4x - 12x +12 (simplyfy each side)
8x + 4 = - 8x +12 (add 8x to both sides)
8x + 4 + 8x = 12
16x + 4 = 12 (subtract 4 from both sides)
16x = 12 - 4
16x = 8 (divide both sides by 16)
x = 8/16
x = 0.5
Shianne and Samoah were working with exponents. Shianne claims that 7^9/7^5=7^4 and samoah argues that 7^9/7^5=7^45 Which one of them is correct? Use the properties of exponents to justify your answer.
Answer:
Shianne is correct as per rules of exponents (Division of exponents with same base is subtraction of powers)
Item 4 The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. An equation is =540. The solution is x= .
Let's set the sum of the angle measures equal to 540 degrees.
139 + 3x + 5x - 10 + 10x - 9 + 3x = 540
Let's combine like terms.
21x + 120 = 540
Subtract 120 from both sides.
21x = 420
Divide both sides by 21
x = 20
A canoe rental service charges a transportation fee and $8 dollars an hour to rent a canoe. Mary and Joe rented a canoe for 6 hours, and the total cost for was $68.
Answer:
transportation fee= $20
Step-by-step explanation:
Giving the following information:
A canoe rental service charges a transportation fee and $8 an hour to rent a canoe. Mary and Joe rented a canoe for 6 hours, and the total cost was $68.
To calculate the transportation fee, first, we need to calculate the total rent cost for 6 hours.
Rent cost= 6*8= $48
Now, the transportation fee:
transportation fee= 68 - 48
transportation fee= $20

2m - n =8 Solve for n
Answer:
[tex] \boxed{\sf n = 2m - 8} [/tex]
Step-by-step explanation:
Solve for n:
⇒2m - n = 8
Subtract 2 m from both sides:
⇒2m - 2m - n = 8 - 2m
2m - 2m = 0:
⇒-n = 8 - 2 m
Multiply both sides by -1:
⇒-n × (-1) = (8 - 2m) × (-1)
⇒n = 2m - 8
The required value of n is equal to n = 2m - 8.
An expression is given in the question ; i.e., 2m - n = 8.
We have to find the value of the 'n' .
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the question ;
The given expression is 2m - n = 8.
Let's solve it to get the value of n.
The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.
So ,
2m - n = 8 can be written as ;
2m = 8 + n
or
n = 2m - 8
Thus , the required value of n is equal to n = 2m - 8.

What are the next two numbers in this sequence?
Answer:
74, 138
Step-by-step explanation:
The numbers seem to be increasing by powers of 2. 14 - 12 = 2 = 2¹, 18 - 14 = 4 = 2², etc. Therefore, the next 2 numbers would be 42 + 2⁵ = 74 and 74 + 2⁶ = 138.

Algebra KPL and LJPL are a linear pair, m_ KPL = 2x + 24, and mLJPL = 4x + 36. What are the measures of ZKPL and LJPL? (2x + 24) (4x + 36) к P
Answer:
64° = ∠KPL116° = ∠JPLStep-by-step explanation:
The sum of the measures of a linear pair of angles is 180°.
(2x+24) +(4x+36) = 180
6x = 120 . . . . . . subtract 60, collect terms
x = 20
(2(20) +24)° = 64° = ∠KPL
(4(20) +36)° = 116° = ∠JPL

Answer: t>3
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form: t>3
Interval Notation: (3,∞)
Step-by-step explanation:
Write the original inequality. 6t + 5 > 23
Subtract 5 from each side to undo addition. 6t > 18
Divide each side by 6 to undo multiplication. t > 3
So our answer is t > 3.

Hey there!!!
According to the question,
Angle P is three less than twice less of an angle Q.
Then, let angle Q be x then angle P is 2x-3.
Now, it has also given that they are supplementary angle.
We know that the sum of supplementary angle is 180°.
Therefore, x+ 2x - 3°=180°.
Or, 3x = 180°-3°
Or, x = 177°/3
Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.
