What is the least common denominator of 4/x * -4/2x^2?

Vanyuwa [196]

The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it

Hope this helps :)

What is the measure of ABC?

leva [86]

Answer:

Step-by-step explanation:

the measure of the chord- chord angle ABC is half the sum of the arcs intercepted by the angle and its vertical angle , that is

∠ ABC = $\frac{1}{2}$ (AC + DE) = $\frac{1}{2}$ (75 + 45)° = $\frac{1}{2}$ × 120° = 60°
