Step-by-step explanation:
I'm 8th grade, G
For this problem, you can start by taking the 35 and dividing it by 5 to get 7. Then you need to take 300 and divide that by 5 to get the right proportions. Then you can take your new number from 300 and divide that by 7, and you should not be on the right path because I'm probably an idiot.
Sorry bout it
Legnth are x and y
x+y=100
one is 16 more than other
x is 16 more than y
x=16+y
x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42
sub back
x=16+y
x=16+42
x=58
the legnsh are
42 cm and 58cm

(r+7)(r-2) (r+7)(r-3)

(r+7)^2 (r-3)
