Answer: x^2 + 9x + 20
Step-by-step explanation:
Foil Method: (a + b) (c + d) = ac + ad + bc + bd
Lets say:
a = x
b = 5
c = x
d = 4
Plugging in the numbers: xx + 4x + 5x + 5*4
Combine like terms:
xx = x^2
4x + 5x = 9x
5 * 4 = 20
You're then left with: x^2 + 9x + 20
Answer:
find using calculator yourself:))
Step-by-step explanation:
pi x r x r = pi x 88 x 88 = answer
what's it look like if like this |__ right /_ acute \__ obtuse
I could explain it, but you have to ask me, other than that the answer is 5(x+7)(9x-4).
