Answer is <span>C) 1/20 of a foot
1/4 -1/5
= 5/20 - 4/20
=1/20</span>
<span>x^2+10x + 25 = (x + 5)^2
missing = 25

It's a lot like solving equations.
3b-7 < 32
Add 7 to each side.
3b < 39
Divide by 3 on each side.
b < 13
Hope this helps :)
Answer:
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
