Answer:

(x + 2)(3x - 4)

3x^2 + 2x - 8

Step-by-step explanation:

Factor out x + 2.

You get: (x + 2)(3x - 4)

Now multiply it out:

(x + 2)(3x - 4) = 3x^2 - 4x + 6x - 8 = 3x^2 + 2x - 8

Please help me. I don’t know what to do.

stiv31 [10]

Answer:

1. B

2. 2

3. See below

Step-by-step explanation:

1. Check the length of the segments

A. UV < XY (4 < 4) False

B. WY < UW (5 < 8) True

C. VW > WY (5 > 5) False

D. UX > YV (10 > 10) False

Midpoint of AC = 8

midpoint of AB = 6

The length of the segment between those points is 8-6 = 2

3. If D is the mid point of EF means that ED is the half of EF

$\frac{4x - 8}{10x + 4} = \frac{1}{2 } \\ {2(4x - 8)} = 10x + 4 \\ 8x - 16 = 10x + 4 \\ - 16 - 4 = 10x - 8x \\ - 20 = 2x \\ - 10 = x$

x cant be negative so D isnt the mid point of EF

What does multiply by the reciprical mean ???

xz_007 [3.2K]

It means multiply by the reciprocal of the number. The reciprocal is 1 divided by the number (x).

So assuming you're number is 3, the reciprocal of 3 would be 1/3.

or

Assuming the number is 0.2, the reciprocal of the number would be 1/0.2
