<em>Hence, option A answers the question.</em>
Answer:
Surface Area A = 490 cm²
Step-by-step explanation:
Surface area of a prism A = 2(w l +h l + h w)
where l = length
w = width
h = height
l = 7 cm; w = 7 cm ; h = 14 cm
Surface Area = 2 { ( 7 × 7) + ( 14 × 7) + ( 14 × 7)}
A = 2 { 49 + 98 + 98}
A = 2 × 245
A = 490 cm²
Answer:
The other endpoint would be (-13, -11)
Step-by-step explanation:
In order to find the coordinates of an end point, we need to note that the midpoint would be the average of the two values. We'll call the unknown point P and we'll start by looking at the x values only.
(1 + Px)/2 = -6 ----> multiply by 2
1 + Px = -12 -----> subtract 1
Px = -13
Now we can do the same with the y values.
(7 + Py)/2 = -2 ----> multiply by 2
7 + Py = -4 ------> subtract 7
Py = -11
