My answers are 13. B ; 14. C ; 15. C.
Answer:
B is the answer.
Step-by-step explanation:
Use power rule: (x^a)^b = x^ab.
Answer:
Length A: 5 ft
Width B: 4 ft
volume = 88 ft³
Step-by-step explanation:
Length A: 8 - 3 = 5 ft
Width B: 8 - 4 = 4 ft
<u>Volume</u>
The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).
Volume of a rectangular prism = width x length x height
Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³
Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³
Total volume = 64 + 24 = 88 ft³
The answer is - 1.5. subtract -2.5 by -1.5
MxM=M^2 (m squared)
Highest variable comes first, so it'd be m^2+5m+6
(m+2)(m+3) is your answer. That is it factored. If that equation equals 0, then m=-2 or -3
