We are asked to find how many terms are in
.

- A term is a thing that's added or subtracted.
So let's compute the number of terms in this expression.
The first term is
.
Is anything added or subtracted from 10y²?
Sure!
is subtracted from 10y².
Also, 8 is added to -3y.
Thus, this expression has 3 terms.
Hope it helps you out! :D

Answer:
its 3
so its
(4x+4)^2-2(4x+4)-5
so first you have to do
(4x+4)(4x+4)
the answer is 16x^2+32x+16
and then you do -2(4x+4) and then you add them so then its
16x^2+32x+16-8x-8-5
and then you just add like terms so its
16x^2+24x+3
and then you insert 0 for x
so the answer is 3
Step-by-step explanation:
Brother one: x
Brother two: x + 15
---
Make them add up to 55 in an equation.
x + (x + 15) = 55
Combine like terms.
2x + 15 = 55
Subtract 15 from both sides.
2x = 40
Divide both sides by 2.
x = 20
Plug 20 for x into brother two.
(20) + 15 = 35
Brother one has saved $20, brother two has saved $35.
