Answer:
1. 142 in.²
2. 190 cm²
Step-by-step explanation:
Both solids are rectangular prisms.
Surface area of a rectangular prism = 2(LW + LH + HW)
1. L = 7 in.
W = 3 in.
H = 5 in.
Plug ok the values into the formula
Surface area = 2(7*3 + 7*5 + 5*3)
= 142 in.²
2. L = 10 cm
W = 3 cm
H = 5 cm
Plug ok the values into the formula
Surface area = 2(10*3 + 10*5 + 5*3)
= 190 cm²
Mean (the average):
is the mean
Median (the middle number when the numbers are ordered):
87
Mode (most repeated number(s)):
74 and 87
Range (difference between the highest and the lowest values):
115-67=48
Answer: The base graph vertically stretched by a factor of 6.

I would solve this by using elimination, because you have opposite coefficients, (7x and -7x)<span />
