Answer:
7/3
Step-by-step explanation:
i hope this works :)
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
Answer:
106.68
Step-by-step explanation:
13.5*12=42
42*2.54=106.68
The two numbers are 21 and -4 because 21×(-4)=(-84). And when you add 21+(-4) you get 17.
