Given : (5b - 9) - 3(8 - 26)
⇒ (5b - 9) - 3(-18)
⇒ (5b - 9) + 54
⇒ 5b - 9 + 54
⇒ 5b + 45
Perimeter is adding the 3 sides together. Since both triangles have the same perimeter set both triangles to equal:
(x+3 + x+3 + x+3) = (x+3 + 2x-3 + x)
Simplify each side:
3x+9 = 4x
Subtract 3x from each side:
x=9
<span>112 is <em>80</em>% of <em>140</em>. <em>80</em>% can be written as 0.80 or 0.8. so the answer is 112</span>
