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
The answer is 4/7 in simplest form
Who eats onion pizza?
anyway, make bases same
1/4 times 5/5=5/20
2/5 times 4/4=8/20
5/20 vs 8/20
8/20 i bigger
2/5 is bigger
actaully depends on how big th pizza is
cheese could be 12 feet wide and the onion could be 12 inches wide
The answer is

first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms

this gives you 3x^2, then you multiple the outer terms

this gives you -21x, then you multiply the inner terms

that gives you 2x, finally you multiply the last terms

that gives you 14, now you combine like terms

now you put all the terms together and end up with your solution
