7/12n is the answer to your question
Answer:
The answer is True.
Step-by-step explanation:
- <u>Estimate the Answer Before Solving Having a general idea of a ballpark answer .</u>
- <u>Or the problem lets students know if their actual answer is reasonable or not.</u>
To factor first multily 100 and 1 and get 100
then find what 2 numbers multiply to get 100 and add to get 20
the numbers are 10 and 10
so
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
X=7
after you remove parentheses you do those steps
