Since 16 and 25 are perfect squares you can factor the first part.
4^2-5^2(b+3)^2
=(4-5(b+3))(4+5(b+3))
=(4-5b-15)(4+5b+15)
=(-11-5b)(19+5b)
Which can be expanded if necessary,
= -209+150b-25b^2
1) Would be c+15 because you can combine 19-4
2) Would be m+2 because you can combine 12-10
Answer:
13 students
Step-by-step explanation:

The rectangular prism has a volume of, 1/4 cubic meter.
Answer:
The scalar factor is 4/3
Step-by-step explanation:
The bottom of triangle B is 16 units, the bottom of triangle A is 12 units. So to find the scalar factor you have to divide B by A:
6/12=4/3
