8. (1)
Area of trapezoid = 1/2(sum of || sides) *perpendicular distance
36 =1/2(x+ y) * 6
36 = ((x + y)*3
36/3 = x + y
12 = x + y
x + y = 12.... (1)
8(2)
It is given that:
x = 2y....(2)
From equations (1) & (2)
2y + y = 12
3y = 12
y = 12/3
y = 4
From equation (2)
x = 2y = 2*4
x = 8

Area of square = 1 square m
Side of square = 1 m
Area of circle = 1 square m
Answer:
C.
Step-by-step explanation:
Easiest and fastest way to determine your answer is to graph the systems of inequalities on a graphing calc. Once you do so, you should be able to see that Choice C is the correct answer.
Answer:
d = 12
c = 4
so I think d > c
Step-by-step explanation:
1 x 12 = 12
0.75 x 4 = 3
12 + 3 = 15
Answer:
x=14.02
Step-by-step explanation:
Use b=
to solve for the missing side in the triangle. You will get a rounded answer of 8.49. Then you multiply that by 2 and subtract that value from 31. Then that will be your answer.
