Answer:
54 sq ft, 24 sq ft, 78 sq ft
Step-by-step explanation:
1. Each side of cube 1 is 3 feet x 3 feet, so each side has an area of 9 square feet. Multiply by 6 sides and the area is 54 square feet.
2. Each side is 2 feet x 2 feet so the area of one side is 4 square feet. Multiply by 6 sides and the area is 24 square feet.
3. 54 + 24 = 78 square feet
I need help with this
Step-by-step explanation:
I think the answer should be C
Answer: A
(2, -4) and (0,4);
x, y x, y
A. y = -4x +4; substitute the pairs
(2,-4)
-4 = -4(2) + 4 = -4; -4 = -4
(0,4)
4 = -4(0) + 4 = 4; 4 = 4
B. y = -4x - 4
(2, -4)
-4 = -4(2) - 4 = -12; -12 ≠ -4
(0,4)
4 = -4(0) - 4 = -4; -4 ≠ 4
C. y = 4x - 4
(2, -4)
-4 = 4(2) - 4 = 4; 4 ≠ -4
(0,4)
4 = 4(0) - 4 = -4; -4 ≠ 4
D. y = 4x + 4
(2, -4)
-4 = 4(2) + 4 = 12; 12 ≠ -4
(0,4)
4 = 4(0) + 4 = 4; 4 = 4
Answer A works out for both ordered pairs.
