Answer 2

Choose the correct simplification of 8x^2(4x + 2x^2 − 1).

32x4 − 16x3 + 8x2
32x4 + 16x3 − 8x2
16x4 − 10x3 + 8x2
16x4 + 32x3 − 8x2

Answer 3

Solve for these

\(8x^2\cdot 4x=?\\
8x^2\cdot 2x^2=?\\
8x^2\cdot -1=?\)

Answer 4

32x^3
16x^4
-8x^2

Answer 5

so d?

Answer 6

Correct

Answer 7

:)

Answer 8

Choose the polynomial written in standard form.

x3y2 + 4x4y + 10x9
x4y2 + 4x4y5 + 10x2
xy2 + 4x3y8 + 10x2
x4y5 + 4x3y2 + 10x2

Answer 9

is it d?

Answer 10

Could you rewrite to see the exponents?

Answer 11

nvm i got it i got 100% :)

Answer 12

Sure :D

Answer 13

im serious :) im happpyyyyyyy

Answer 14

Glad to hear!

Answer 15

lol

Answer 16

The lengths of two sides of a triangle are shown below:

Side 1: 3x^2 − 4x − 1

Side 2: 4x − x^2 + 5

The perimeter of the triangle is 5x^3 − 2x^2 + 3x − 8.

Part A: What is the total length of the two sides, 1 and 2, of the triangle? (4 points)

Part B: What is the length of the third side of the triangle? (4 points)

Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer. (2 points)
