Answer:1.A
2.D
Step-by-step explanation:
To determine the lateral surface area of the rectangular prism, the equation would be,
Lateral area = 2 x (HxL + HxW)
where H is height, L is length, and W is width. Substituting,
lateral area = 2 x (8x13.2 + 8x6) = 307.2 ft²
Martina's estimation is quite near to the calculated value which means that her estimation should have been really reasonable.
1)n-16
2)8n
3)1/2n + 20
4)4n - 20
5)length + width
6)r × t + 10
7)(t - x) × 5
This question is easy the answer is x=-5
