I think sherry because 450 divided by 9 equals 50mph and jose drives 65mph.
Answer:
D.) $3.99
Step-by-step explanation:
Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)
Multiply all terms by x and cancel
xx+-15=2x
x^2-15=2x simplify both sides
x^2-15-2x=2x-2x subtract 2x from both sides
x^2-2x-15=0
(x+3)(x-5)=0 factor left side of equation
x+3=0 or x-5=0 set factors equal to 0
x=-3 or x=5
hope this helps!
