Step-by-step explanation:
n cups -> 195n calories
cups -> 195 * =
(8j3 - 5j2 - 5) - (6j3 - 12j2 + 8j - 7) =
(8j3 - 6j3) - (5j2 - 12j2) - 8j - (5-7) =
2j3 - (-7j2) - 8j - (-2) =
2j3 + 7j2 - 8j + 2
The correct answer is D. 2j3 + 7j2 - 8j + 2
Answer:
its B E F
Step-by-step explanation:
hope this helps
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.
