Answer:
Step-by-step explanation:
Remark
The surface area is the area of all six sides when the object is a box.
Formula
SA = 2*L*w + 2*L*h + 2*w*h
Givens
L = 6 ft
w= 3 ft
h = 2.5 feet
Substitute and Solution
SA = 2*6*3 + 2*6*2.5 + 2*3*2.5
SA = 36 + 30 + 15
SA = 81
The answers are over 4 and 3
Answer:
2/3
Step-by-step explanation:
Parallel lines have the same slope and will never intersect
slope = (y-y') / (x-x') = (3 - (-1)) / (3 - (-3)) = 4/6 = 2/3
Simplify

, as there is 9 as a factor. The new form is
Then, add 18 and 3 to get

The correct answer is B.
