Answer:
105
For the 4 triangular faces, find the area with 1/2 × base × height = 1/2 × 5 × 8 = 20
4 triangles -> 20 × 4 = 80
The area of the square base is 25
80 + 25 - 105
The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
B. 4.
You can get this by setting them equal to each other and getting all of the x terms to one side. Then get the number values to the other and divide the coefficient away.
