Answer:
C. x²+3x-28
Step-by-step explanation:
f(x) = x +7
g(x) = x -4
f(x) · g(x) = (x-4)(x+7)
= x²+7x-4x-28
= x²+3x-28

The probability of the spinner landing on an even number or a multiple of 3 is ___?
13/18
1/3
7/9
2/3
5/6
This answer to this question is 32.
4x - 2y = 7....multiply by 3
3x + 6y = 9
-------------
12x - 6y = 21 (result of multiplying by 3)
3x + 6y = 9
-------------add
15x = 30
x = 30/15
x = 2
4x - 2y = 7
4(2) - 2y = 7
8 - 2y = 7
-2y = 7 - 8
-2y = -1
y = 1/2
solution (2,1/2)
