The rectangle below has a area x^2-x-72 square meters and a length of x+8 meters what expression represents the width of the rec
mixer [17]
ANSWER

w = (x - 8)

EXPLANATION

The given rectangle has area,

A = {x}^{2} - x - 72 \: {m}^{2}

It was given to us that, the length of the rectangle is l=(x+8)

To find the width, we need to factor, the expression for the area.

We split the middle term to get,

A = {x}^{2} - 9x + 8x- 72

We now factor by grouping;

A = x(x - 9) + 8(x- 9)

A = (x + 8)(x - 9)

We know that area of a rectangle is

A = l \times w

Hence the width of the rectangle is,

w = (x - 8)

What is the solution to this equation? <br> log_7 (5 + 11x) = 2
11111nata11111 [884]

Answer:

x = 4

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n , then x = b^{n}

Given

log_{7} (5 + 11x) = 2 , then

5 + 11x = 7² = 49 ( subtract 5 from both sides )

11x = 44 ( divide both sides by 11 )

x = 4
