The length of a rectangular park is 20 feet longer than the width of the park. If the lenght of the park is 36 feet, what is the
lara [203]

Below is a labeled rectangle:

length = w + 20

we know length is 36 so we plug that in:

36 = w + 20

We need to isolate w and to do that we must subtract 20 from both sides:

(36 - 20) = w + (20 - 20)

16 = w + 0

w = 16

width is 16 feet

Hope this helped!

What number makes the expressions equivalent? Enter your answer in the box. 12 (–1.4m + 0.4) = m + 0.2
True [87]

Answer:

0.2584

Step-by-step explanation:

12 (–1.4m + 0.4) = m + 0.2

Open the bracket

-16.8m + 4.8 = m + 0.2

collect like terms

-16.8m - m = -4.8 + 0.2

-17.8m = -4.6

Divide both sides by -17.8

m = 4.6/17.8 = 46/178

m = 0.2584
