Answer:
Step 2
Step-by-step explanation:
Fiona did mistake step 2.
Use the distributive property to multiply -3 times each term in the trinomial.
The correct result is
-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21
Fiona written -6x instead of + 6x.
That's the error.
The answer is "Step 2"
Hope you will understand the concept.
Thank you.

Answer:
f(x+h) = 4x² +8xh +4h² -9x -9h +7
Step-by-step explanation:
Put (x+h) where x is in the original definition of f(x):
f(x+h) = 4(x+h)² -9(x+h) +7
It is a little hard to tell what "do not factor" means, and whether this is considered to be a factored form.
If we expand the above, we get ...
f(x+h) = 4x² +8xh +4h² -9x -9h +7
Your picture is a bit blurry. What is the equation on WX and on ZY?
Answer:
Let the length be l, width w and height h, then
Volume = length x width x height
l = 10cm, w + h = 18cm
V(h) = 10(18 - h)h = 180h - h^2
V(h) = 180h - h^2
