Answer:
6x + 2 ( x - 4) = 8 + 4 ( x + 2)
6x + 2x - 8 = 8 + 4x + 8
<em><u>Arranging</u></em><em><u> </u></em><em><u>like</u></em><em><u> </u></em><em><u>terms</u></em><em><u> </u></em>
6x + 2x - 4x = 8 +8 - 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2
A=P×(0.8)
A is the price after the markdown
P is the original price
0.8 is the multiplier because 1-(80/100)=0.8
80/100 is the same as 80%, which is the remaining value when 20% of the value of the item is deducted.
4 rectangles are 6 x 4
4 triangles are 4x 4
1 square is 6x 6
Area :
6 x 4 = 24 x 4 = 96
1/2 x 4 x 4 = 8 x 4 = 32
6 x 6 = 36
96 + 32 + 36 = 164 square inches.
The answer is A
