A=LW
192=(13+x)((9+x)
192=117+22x+x^2 (subtract 192 from both sides)
x^2+22x-75+0 (factor)
(x+25)(x-3)=0
so x=-25 or 3
Check work
since we are adding x it can only be the positive solution so x=3 so the new dimensions are:
L=13+3=16m
W=9+3=12
check: 16*12=192 so the answer is correct hope this helped

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000

Paraphin [41]

Answer:

P = t - f

Step-by-step explanation:

First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.

let p = pages left to fill

let T = total pages needed

let F = pages already filled
