to get an A, she needs >=160 points and she already has 125 points
let 'x' be the number of points on the last part of her project then
125 + x >= 160
x >= 160 - 125
x >= 35
Sarah needs at least 35 points on the last part of her project.
Multiplying binomial and polynomials can be easy as long as you follow the steps for example:
Let's say you were multiplying 3x-3 and x+2
(3x-3)(x+2)
remember FOIL
OR think about it like this(see attatchment)
3x^2 + 3x -6 is what you should get
(1) You can see that the 6 is being added to both sides.
You are trying to make both sides equal by adding 6, so it would be the Addition Property of Equality.
(2) 4 is being divided into both sides.
It would be the Division Property of Inequality. (you are dividing by 4 to make both sides equal)
"B" is the answer.
I hope this helps!
