8 0

Answer: D

<u>Step-by-step explanation:</u>

f(x) = 2x     g(x) = x² - 1

f(g(x)) = 2(x² - 1)

         = 2x² - 2

g(f(x)) = (2x)² - 1

         = 4x² - 1

What is 10+3c+5d-7c+d
kumpel [21]
Hey!


To simplify the equation provided we must first start off by grouping like terms.

<em>Original Equation :</em>
10 + 3c + 5d - 7c + d

<em>New Equation {Grouped Like Terms} :</em>
3c - 7c + 5d + d + 10

Now we add similar elements.

<em>Old Equation :</em>
3c - 7c + 5d + d + 10

<em>New Equation {Added Similar Elements} :</em>
-4c + 5d + d + 10

Next we add the other similtar elements.

<em>Old Equation :</em>
-4c + 5d + d + 10

<em>New Equation {Add Similar Elements} :</em>
-4c + 6d + 10

<em>So, this means that the equation 10 + 3c + 5d - 7c + d simplified is</em>  -4c + 6d + 10.

Hope this helps!
