Answer:
C. 591.5 ft^3
Step-by-step explanation:
1/2 (13*13) = 84.5
84.5*7 = 591.5
The second option: 4x² - x + 1
All you have to do is add the like terms:
3x² + x² = 4x²
4x - 5x = -x
-2 + 3 = 1
Combine all the results and you will get your solution!
Yes you would subtract but only if your subtracted it from a negetive
the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84 inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.
