Answer:
90.25π
Step-by-step explanation:
The formula for solving the area of a circle is πr².
r is the radius. We can find the radius by splitting the diameter in half: 19/2 = 9.5.
We can apply the area formula and we get π9.5² and the answer is 90.25π.

Answer:
2x + 15
Step-by-step explanation:
When you subtract an expression from another expression, it will be on the right side of the subtraction sign.
(4x + 9) - (2x - 6)
First, let's distribute the negative sign.
(4x + 9) - 2x + 6
Now combine like terms.
4x - 2x + 9 + 6
2x + 15
This is the fully simplified expression.
Hope this helps!
C is the answer. Solutions to a polynomial are numbers that, when plugged into the equation, make the equation equal zero
So if you plug 3, -1, or 2 into x^3 - 4x^2 + x + 6, it will equal zero.
