Hello, I'm new to homeschooling and I have a question. Do teachers approve of this answer??? I don't know what happens when I submit this. Thanks!

see explanation

Step-by-step explanation:

product means multiply

Given

(2x - 4)(5x² - 2x + 6)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(5x² - 2x + 6) - 4(5x² - 2x + 6) ← distribute both parenthesis

= 10x³ - 4x² + 12x - 20x² + 8x - 24 ← collect like terms

= 10x³ - 24x² + 20x - 24

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
