Answer:
the answer is x + 9
Step-by-step explanation:
3 times x equals 3x and 3 times 3 equals 9 -2X
you need to add like terms together
3x+2x=5x
and then 9 is by itself
so x+ 9 is the answer

Answer:
D. 105 ft²
Step-by-step explanation:
The total surface area is the sum of the base area and the triangular face areas.
Area of base:
A = s²
A = (7 ft)² = 49 ft²
Area of 4 triangles:
A = 4(1/2)bh
A = 2(7 ft)(4 ft) = 56 ft²
Total surface area:
base area + triangle area = 49 ft² +56 ft² = 105 ft²
