NEED HELP ASAP!

18. Simplify the expression:

-x(6x - 7)

A. -6x^2 + 7x
B. 5x^2 - 6x
C. 6x + 7x
D. -6x - 7x

Answer 1

Well, do it. What's your plan.

Never post a problem with no work shown.

Answer 2

I am here since I need help on the problem. That's why I came here, to learn how to solve the problem.

Answer 3

Just post any work you have done regarding this question. it doesn't matter if it's wrong. We can help you out and to fix the problems where you made mistakes on:)

Answer 4

You MUST have SOME idea. Give us ANYTHING. We'll be delighted.

Answer 5

I think the answer is C since -x * -6x would be 6x then -x * -7 would give you a positive so 6x + 7x?

Answer 6

-x * -6x
But you had just positive 6x
\(-x(\color{red}6x - 7)\)

Answer 7

So -6 so either A or D?

Answer 8

a(b+c)

Use Distributive Property of Multiplication over Addition

a(b+c) = a*b + a*c

If you get 6x, which is where you started, something went wrong.

Answer 9

So A?

Answer 10

Let the notation help you. Go ahead and write things out.

-x(6x - 7) = (-x)(6x) + (-x)(-7) = -6x^2 + 7x

You can demonstrate the entire process in just a few characters.

Answer 11

Yay. Thank you so much.

Answer 12

Could you help me with one more?
