Answer:
33 sq in
Step-by-step explanation:
Area of each triangular face is 1/2×3×4 = 6sq in
Hence total area of four(4) faces is 6×4 = 24sq in
Area of base is 3×3 = 9sq in
Hence Total area of pyramid is 24+9 = 33sq in
The answer is -40
-2(12-2(-4))
-2(12+8)
-2x20
-2x20 = -40

Answer:
47
Step-by-step explanation:
First, plug in the numbers.
x = -3 and y = 2.
-3(-3) + 4(2) - 5(-3)(2)
Simplify by multiplying.
-3 * -3 = 9
4 * 2 = 8
-5 * -3 * 2 = 30
Your new equation is:
9 + 8 + 30 = ?
Simplify by adding. 9 + 8 + 30 = 47
5 inches by 8 inches are both dimensions.
