Answer:
C
Step-by-step explanation:
x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3) 
or delta:
∆=2²-4*1*(-15)=4+60=64
√∆=8
x1 = (-2+8)/2 = 3
x2=(-2-8)/2=-5
and 4x+20 = 4(x+5)
The same is (x+5), so it is GCF. answer C

Answer:
<u>Hanna is 8 years old.</u>
Step-by-step explanation:
Hanna = x
Tina = 4x
Sum = 40.

x = 40/5
x = <u>8</u>.
Hanna is <u>8 years</u> old.
