<h2>
∴The perimeter of the trapezoid= 30 feet</h2>
Step-by-step explanation:
Given that the parallel bases of a trapezoid measure 2 feet and 6 feet and the legs measured 9 feet and 13 feet.
∴The perimeter of the trapezoid = sum of all sides
= (2+6+9+13) feet
= 30 feet
The variable in this equation is b, therefore we have to calculate the value of b.
-38=2b+25-(-7b)
-38=2b+25+7b
2b+7b=-38-25
9b=-63
b=-63/9
b=-7
Answer: the value of the variable is b=-7
We can check it out this answer:
-38=2b+25-(-7b)
-38=2(-7)+25-(-7(-7))
-38=-14+25-49
-38=-38
4+2i because you can’t have a negative square root
