Answer: x^2+9x+20
Step-by-step explanation:
To find the area you multiply the sides so it should be (x+4)(x+5) which is x^2+9x+20. Good luck!
Answer:
D
Step-by-step explanation:
if x= number of hours replace the x by 9
so you have 5×(1.50)^9+10=
5×(192.21)+10 = 202.21 so 202 will be nearest whole number
Step-by-step explanation:
you collect like terms from both sides that is, the variables on one side and the constants on the other side
C is not continuous.
Continuous functions have connected graphs; this indicates that every possible value of x has a value of y associated with it. In this case, that says that every possible radius measurement has a number of tennis balls associated with it. The problem with this is that we cannot have a fractional part of a tennis ball, so it is not continuous.
