It would be: 2/5 /2 = 2/10
so your answer is 2/10
Answer:
A=8
Step-by-step explanation:
If you use the formula 30-60-90 which is a-radical 3a-2a
since the hypotenuse is 2a it equals 16
therefore if its 2a all you need to do is divide it where then you get 8.
The roots from smallest to greatest are -3, 1, and 5/2 or (2 1/2).
At those two x-intercepts, I know that x=2 and x=-2.
to get this, I know that there are two factors set to 0.
x+2=0 and x-2=0
so, if you multiply (x+2)(x-2)=y
then you will have standard form
x^2+2x-2x-4=y
y=x^2-4
No 8-12 is like 3:4 and 3-6 is like 1:2
