Solve. 8 – 3x – x = 12 x =?

poizon [28]

You have to isolate x. First you start off by adding the like terms which is -3x and -x. By adding them you get -4x.

8 - 4x = 12

Then you subtract 8 on both sides since it is positive to isolate x.
-4x = 4

Then you divide -4 by both sides and get x=4/-4

4/-4 is simplified to -1 so the answer is x= -1

Answer:

(a)

Shortest Side of the trapezoid =6 yds

Longest Side =8 yds

(b)42 Square Yards

Step-by-step explanation:

Part A

In the Trapezoid, Width =6 yd

Since the shortest side of the playground and its width have the same dimension, then:

Shortest Side of the trapezoid =6 yd

Longest Side =6+1+1=8 yd

Part B

Area of the Playground

In the trapezoid

a=6 yd, b=8 yd, h=Width=6 yd

Area of a trapezoid $=\frac{1}{2}(a+b)h$

$Therefore: Area=\frac{1}{2}(6+8)*6\\=14*3\\=42$ Square Yards$
