Answer:
1. 500
2. 126
3. 615
Step-by-step explanation:
Area of a parallelogram formula: A = bh
20 x 25 = 500
7 x 18 = 126
20.5 x 30 = 615
5(4+y) is the correct answer, you would be adding 4 and y then multiplying the sum by 5
Answer:
4000 
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000 
Answer:
31:1
Step-by-step explanation:
Answer:
x = 34
Step-by-step explanation:
x and 146 are supplementary angles so they add to 180 degrees
x+146 = 180
Subtract 146 from each side
x+146-146= 180-146
x =34
