Step-by-step explanation:
PEMDAS
-6 x 12p = -72p
-6 x -8n = 48n
48n - 47n = n
20
Explanation:
20 + 4 = 24. Therefore 24-20=4
Answer:
Area is 126.5 inches^2
Step-by-step explanation:
Mathematically, to calculate the area of the trapezoid, we use the following mathematical formula;
A = 1/2(a + b) h
here, a and b represents the two parallel sides which is 9 and 14 inches here and h which is the height is 11
Plugging these values into the equation, we have
A = 1/2(9 + 14)11
= 1/2(23)11 = (23*11)/2 = 126.5 inches^2
Answer:
do the first part yourself but for part b you have to do this
Step-by-step explanation:
(10+8)×(8+8)×(8+10)=5184mm
