Step-by-step explanation:
3 to the power of 2 is 9
5 times 2 is 10
10 plus 9 is 19
Answer:
460 mi²
Step-by-step explanation:
The surface area consists of 3 rectangles of the sides, and the two base triangles.
The front rectangle has dimensions of 10x11, so it's area is 110 in²
The left side rectangle has dimensions of 10x11, so it's area is 110 in²
The right side rectangle has dimensions of 12x11, so it's area is 132 in²
The top and bottom triangles have a base of 12 and a height of 8, so their area is
A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²
The total surface area is 110 + 110 + 132 + 108 = 460 mi²
A. 48 = 12 + 20 + x
If you use this equation then you can do 12 + 20 = 32 and then you can do 48 - 32 = 16 so x = 16
