5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

-3

Step-by-step explanation:

We need to use the distributive property a couple times to expand the parentheses.

Remember that when expanding parentheses, we find the sum of the products of the outside term with each of the inside terms.

5(x - 4) = 5 * x + 5 * (-4) = 5x - 20

-(2x + 5) = -1 * 2x + -1 * 5 = -2x - 5

Now we have:

5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

Combine all the terms with x:

-x - 20 = 6x + 1

7x = -21

Divide by 7:

x = -21/7 = -3

The answer is thus -3.

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
