4(2x+3)=-6+5x

Multiply the bracket by 4

(4)(2x)(4)(3)=-6+5x

8x+12=5x-6

Move 5x to the other side. Sign changes from +5x to -5x.

8x-5x+12=5x-5x-6

8x-5x+12=-6

3x+12=-6

Move 12 to the other side. Sign changes from +12 to -12.

3x+12-12=-6-12

3x=-18

Divide by 3 for both sides

3x/3=-18/3

Cross out 3 and 3, divide by 3 and then becomes x

x=-6

Answer: x=-6

Answer:

See below.

Step-by-step explanation:

I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.

♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

$AL=\frac{OR+CE}{2}$

Use this equation and substitute values given in each problem, then solve for the missing information.

1. AL = x, CE = 9, OR = 5

$x=\frac{9+5}{2}=7$

2. AL = <em>m</em> - 4, CE = 15, OR = 17

$m-4=\frac{15+17}{2}=16\\\\m-4=16\\\\\\m=20\\\\AL=20-4=16$

3. OR = y + 5, AL = 15, CE = 18

$15=\frac{(y+5)+18}{2}\\\\15=\frac{y+23}{2}\\\\30=y+23\\\\7=y\\\\OR = 7+5=12$

Answer: 0

To find this answer, we replace x with 0 in the g(x) function

g(x) = -2x

g(0) = -2*0

g(0) = 0
