First add like terms
-8 - x = -3x
-8 = -2x [added x to both sides]
x = 4 [divided both sides by -2]

therefore x = 4

Consider this expression.

schepotkina [342]

Answer:

$9m^2 + 17m- 9$

Step-by-step explanation:

Given

$7m^2 + (2m - 1)(m + 9)$

Required:

Simplify

We start by opening the bracket

$7m^2 + (2m(m + 9) - 1(m + 9))$

$7m^2 + 2m^2 + 18m - m - 9$

Collect Like Terms

$9m^2 + 17m- 9$

Hence, the equivalent expression is $9m^2 + 17m- 9$

A swimming pool has a perimeter of 80 feet the short side measures 16 feet what is the length of the longer sides of the pool

svlad2 [7]

2 x (L + W) = Perimeter

2(L + 16) = 80 Then divide both sides by 2

L + 16 = 40 Then subtract 16 from both sides

L = 24 feet
