Answer:

Step-by-step explanation:
we have

When multiply two fractions:
Multiply the numerators of the fractions to get the new numerator.
Multiply the denominators of the fractions to get the new denominator
so

(x-3) cancels out

Answer: 8
Step-by-step explanation:
Im guessing either 2/3*570 or 1/3*5700
Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!
