Answer:
(x + 7) (x - 3)
Step-by-step explanation:
Find 2 numbers that add to 4 and multiply to -21
(x + 7) (x - 3)
The complete formula for circumference is:

Since we know the circumference of the circle is 314 inches, we can then solve for d, the diameter:

Using 3.14 for pi, we get:

Then solve for d:

And now we know the diameter of the circle is 100 inches.
Answer:
a^2-ab+b^2
Step-by-step explanation:
factorize both of them.
Answer:
D. y=2x-2
Step-by-step explanation:
once you plot the points, you see that the y-intercept is -2 and the rise over run is 6/3. you simplify 6/3 by dividing and get 2x. So y=2x-2.
