The width of the rectangle is 10 more than the length p=2l+2w 120=2l+2(l+10) = h e l p

if you have 120 =2L +2(L+10)

distribute the 2nd part to get:

120 = 2L +2L +20

120 = 4L+20

100=4L

 L = 100/4 = 25

length = 25

 width = 25+10 = 35

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
