-4x^2-5(x+3)+x^2
First, combine like terms.
-4x^2+x^2= -3x^2
-3x^2-5(x+3)
Distribute the 5.
-3x^2-5x-15 <=== the simplified answer
I hope this helps!

Answer:
The midpoint is (1, 4.5)
Step-by-step explanation:
To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is
2/2 is 1 there is only one choice that has an x that is 1. It doesn't hurt, nor take much time to confirm with the y's. 0+9 is 9. And 9/2 is 4.5.
So the midpoint is (1, 4.5)
Answer:
25
Step-by-step explanation:
5+5=10 10+5=15 15+5=20 20+5=25
The polynomial simplifies to an expression that is a linear binominal with a degree of 1.
Put the bottom middle of the protractor on pt Q
Then put the bottom of the protractor on QR
Then whatever degree is on QP is your answer to the first question.
The answer to the second question depends on what angle you got.
90> = Acute
90 = Right
90< = Obtuse
