Answer:
1: X= 8, 2: 2/5 or 0.4
Step-by-step explanation:
1: 2(2x + 1) + x = x + 2x + 18
5x + 2 = 3x + 18
2x = 16
x = 8
2: 2x + x + 2x = 10 + x
5x = 10 + x
4x = 10
x = 4/10
x = 2/5
x = 0.4
Since two of the sides are perpendicular that means they both have a right angle so the correct answer is C.
$400 * 0.13 * 3 = $156
