Answer:
<h2> f(-7) = 249 </h2>
Step-by-step explanation:
To find f(-7) , substitute the value of x that's - 7 into f(x). That is for every x in f(x) replace it with - 7
We have
We have the final answer as
<h3>f( -7) = 249</h3>

Answer:
28.9
Step-by-step explanation:
Using cosine, we get the equation cos(21)=x/31. Solving cos(21), we get about 0.933. Then we multiply by 31 to get about 28.9.
Answer: Distributive property of the multiplication.
Step-by-step explanation:
You did not post Gretchen's expression, but i gues that it is 3*(x + y)
I guess that it is the distributive property of the multiplication.
For 3 numbers, A, B and C, we have that:
A*(B + C) = A*B + A*C
here we have:
3*x + 3*y
We can do the inverse process to the distributive property, and get:
3*x + 3*y = 3*(x + y)
which i guess is Gretchen's expression.
