Answer:
y^2 + 4y + 3
Step-by-step explanation:
(y + 3)(y + 1)
(y*y) + (y*1) + (3*y) + (3*1)
y^2 + y + 3y + 3
y^2 + 4y + 3
Best of Luck!
First we have to combine like terms. 4x² is one term. -8x is another term. -7 is another term. poly = "many" ⇒ polynomial = many terms
(4x² - 8x - 7) + (-5x + 16)
4x² - 8x - 7 - 5x + 16
Combine like terms.
Step 1: 4x² has no other terms with x² so it stays by itself.
Step 2: -8x and -5x are like terms because they both have x.
So -8x -5x = -13x (You put two negatives together)
Step 3: -7 and 16 don't have any x with them. -7 + 16 = 16 - 7 = 9
Now we put all the answers of the steps together.
Step 1: 4x²
Step 2: -13x
Step 3: 9
So the answer is 4x² - 13x +9
And it's a polynomial because there are three terms = "more than one term"
Yes, is would be d. i just took the test
Answer:
Step-by-step explanation:
9 1/3 is the same as 28/3 i got that by multiplying 9(3)=27 after that add 1 which equals 28 so that would make 28/3 after this just divide (28/3)/5 (btw the ilttle dash means to divide looks like this ( / ) after that) it gives you 1.86666667 if you have a calculator just hit math enter enter
Mark has 9. Chole has 2. Altogether, they have 11. Chole had 6, but gave away 4, leaving her with 2. Mark gets 4 apples to add to his 5, giving him 9.
