The commutative property of multiplication.
Your answer is b. hope this helps :)
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
Step-by-step explanation:
To transform a function vertically, add 3 to the constant.
So the function is
Graph the function in desmos to show the translation vertically if you want proof
