Answer: 9x²-81x

Step-by-step explanation:

1. Reorder the terms like this: (9x)• (x-9)

2. Remove unnecessary Parentheses like this: 9x•(x-9)

3. Distribute 9x through the Parentheses like this:

9x would become 9x² (because I combined 9x and 9x which become 9x²)

(x-9) would become -81x (so if you need further explanation I took the (x-9) and made it -9x then multiplied it by the 9x because of distributive property.)

The solution: 9x²-81x

DE is tangent to Circle C at point D. <br><br> What is the measure of Enter your answer in the box.
creativ13 [48]

Answer:

39°

Step-by-step explanation:

A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.

That makes m<D = 90.

m<D + m<C + m<E = 180

90 + 51 + m<E = 180

m<E = 39
