Answer:
16 sq meters
Explanation
Surface area is the area of the figures combined. Find area of base and triangles then add.
2×2=4
2×3÷½=3
since there are 4 triangles you do 3×4
12+4= 16

Answer:

Step-by-step explanation:
When you multiply two exponents together with the same base, the exponents get added
Here the base is the same ie b
So 
The constants multiply in the usual sense so 7(-9) = -63
Answer is 
Answer:
y = (x + 4)²
Step-by-step explanation:
Given equation is,
y = x²+ 8x + 16
By using identity (a + b)² = a² + 2ab + b²
y = x² + 2(4)(x) + 4²
Here a = x and b = 4
y = (x + 4)²
Therefore, factored form of the given equation is y = (x + 4)²
