Step-by-step explanation:
Answer:
D, 30%
Step-by-step explanation:
you move the decimal point twice to the right
2^2=4 so divid 36/4 is 9 and 4*2=8 now subtract 9-8=1 next 36/1 = 36 same on top is 8 now 36-8=28. 28 - 8 is 20 then 20-8= 12 answer is 12
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
