Answer:
-40
Step-by-step explanation:
f(5)= -(5)^2-3(5)
-25-15=-40
Formula for volume of cylinder is area of base time height
area of base equal pir^2 =3,14*(2,5)^2 = 3,14 *6,25 = 19,625 inches squared
V=area time height
170 = 19,625 *h
h = 170/19,625 = 8,662 inches
its A.
Step-by-step explanation:
its B
You cannot assume the angles add to 90, but you know since BD is an angle bisector that ABD is equal to DBC, or x-5=2x-6
x=1. this is the correct solution to the equation but gives negative angles when plugged in which isn't possible. there must be something wrong work the question
Answer: Associative Property
This equation would be the associative property because you would have the ability to add or multiply these numbers, regardless of how they were grouped together
