How the heck do I do this? And what’s the answer?
stira [4]

Answer:

Option A

Step-by-step explanation:

We need to find two expressions that, when simplified, give the same results.

1) First, simplify the expression stated in the question. Multiply each of the terms in the parentheses by the number that is next to them. This would mean you have to multiply both 9x and -6 by \frac{2}{3}. You also have to multiply \frac{1}{2}x and -\frac{1}{2} by 4. Then, simplify.

\frac{2}{3}(9x-6) + 4 (\frac{1}{2} x - \frac{1}{2})\\\frac{18}{3}x- \frac{12}{3} + \frac{4}{2}x -\frac{4}{2} \\6x - 4 + 2x - 2

2) Now, combine the like terms.

6x - 4 + 2x - 2

8x - 6

So, we need to find which of the expressions listed equal 8x - 6.

3) Let's try option A. Do the same as before. Multiply each of the terms in the parentheses by the number that is next to them. So, multiply 4x and -12 by \frac{3}{4}. Also, multiply 30x and 18 by \frac{1}{6}. Then, combine like terms and simplify.

\frac{3}{4} (4x-12) + \frac{1}{6}(30x + 18)\\\frac{12}{4}x-\frac{36}{4} + \frac{30}{6} x + \frac{18}{6}   \\3x - 9 + 5x + 3 \\8x - 6

This also equals 8x - 6. Therefore, option A is the answer.

Are you sure the options are what u have written above? because sqrt of 5x=sqrt of 5x,
sqrt of 20x=2•sqrt of 5x,and sqrt of 80x= 4•sqrt of 5x..
