1) x^2=64 is the same as x=the root of 64 which gives us: (+-)8
2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7

Here you can only use PQ formula in all the others, just as I did in the question number 2</span>
Answer:
its B
Step-by-step explanation:
because if you flip e to the other side of the y-axis you'll get (2,4) and do the same with the letters and that's your answer.
Y=x/2-2 -> y+10=x/2 -> x=2(y+10)
I am not to sure but I think that it is 111.804 inches^3 I hope I am right if not I am really sorry.
