Answer:

=14x² −3x −1

Step-by-step explanation:

simplifying step-by-step.

9x2+5x2+5x−3−(8x−2)

Distribute the Negative Sign:

=9x2+5x2+5x−3+−1(8x−2)

=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)

=9x2+5x2+5x+−3+−8x+2

Combine Like Terms:

=9x2+5x2+5x+−3+−8x+2

=(9x2+5x2)+(5x+−8x)+(−3+2)

=14x2+−3x+−1

Answer:

=14x2−3x−1

What is the exact area of a circle with a diameter of 10 cm? a. 5πcm^2 b. 10πm^2 c. 25πcm^2 d. 100πcm^2

dalvyx [7]

Answer:

Step-by-step explanation:

a= $\pi$ r^2

To find the radius, divide the diameter by 2

r=d/2

r=10/2

r=5

a= $\pi$ r^2

a= $\pi$ 5^2

a=25 $\pi$

So, choice C is correct

Hope this helps! :)
