Answer:

see the explanation

Step-by-step explanation:

we have

<em>Felicia</em>

$-5(3x+2)+10x$

Apply distributive property

$-5(3x)-5(2)+10x$

$-15x-10+10x$

Combine like terms

$-5x-10$

Let

a ----> the missing term with coefficient x in Gregory's expression

b ----> the missing constant term in Gregory's expression

$-12-4x+ax+b$

equate Gregory's expression to Felicia's expression

$-12-4x+ax+b=-5x-10$

$-12+b=-10$ -----> $b=2$

$-4x+ax=-5x$ ------> $a=-1$

Gregory's expression is

$-12-4x+2-x$

therefore

The missing terms are 2 and -x

Two thirds.
1/3 +1/3 = 2/3.
You don’t add the denominator (bottom terms), you only add the numerators (the top terms)

polet [3.4K]

It is given in the question that

$h(x) = (fog)(x) = x^2 -81$

And $x^2 -81$

can also be written as

$(x^2 -40) -41$

Therefore,

$(fog)(x) = (x^2 -40)-41$

$f(g(x)) = (x^2 -40)-41$

That gives,

$g(x) = x^2 -40, f(x) = x-41$
