Answer:
10 feet
Step-by-step explanation:
base= x feet
height=(6+x) feet
area= (6+x)x=160
=6x+x²=160 ==> x²+6x-160=0
factories the eqn obtained....
(x-10)(x+16)=0
x= 10 or -16
since length cannot be negative, x=10
since the base = x feet
base=10 feet
60
720÷60=12
60×12=720
No
No, because the input 1 occurs twice and has 2 different y-values associated with it.
