Answer:
8.9
Step-by-step explanation:
The answer is 8.9 because two negatives divided by each other equals a positive. In this case, there are two negatives so you know the answer will be a positive. In the end when you divided –65.86 ÷ (–7.4), you get 8.9!

(You can also type it into your calculator if you have one, and you should hopefully get the same answer.)
Answer:
2x3+15x2+25x−6
Step-by-step explanation:
Multiply each term in the first expression by each term in the second expression and combine like terms.
Answer:
a). -6x³ - 12x² b). -12 c). 12
Step-by-step explanation:
a). (g x f)(x) can also equal f(g(x))
= f (2x +4)
= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²
= -3(2)²
= -12
c). g(h(3))
h(3) = 3x-1/2
= 3(3) - 1 / 2
= 4
g(4) = 2x + 4
= 2(4) + 4
= 12
Method 1.
Use 
Method 2.
Use distributive property: (a + b)(c + d) = ac + ad + bc + bd
