Solve the equation: 3(-x+4)=20x-7

1 answer:

3 0

1 Regroup terms
3(4−x)=20x−7

2 Expand
12−3x=20x−7

3 Add 3x to both sides
12=20x−7+3x

4 Simplify
20x−7+3x to 23x−7
12=23x−7

5 Add 7 to both sides
12+7=23x

6 Simplify 12+7 to 19
19=23x

7 Divide both sides by 23
19/23 =x

8 Switch sides
x= 19/23

Answer:

26.75 units²

Step-by-step explanation:

This shape can be split into 3 triangles and a square. Find the area of each shape then add them all up.

$A(Square)=2(2)=4\\\\A(Triangle)=\frac{1}{2}(2)(2)=2\\\\A(Triangle)=\frac{1}{2}(5)(2)=5\\\\A(Triangle)=\frac{1}{2}(9)(3.5)=15.75\\\\A(Shape)=4+2+5+15.75=26.75$

Therefore, the area of the shape is 26.75 units².
