Answer:
<em>approximately 52.752 or 16.8 </em>
<em />
Step-by-step explanation:
- First find the radius
a) we know the diameter so we can use the formula r=d/2 to solve for the radius
b)16.8/2 =8.4
2. Then we substitute into the equation
a)2
r
b)2
(8.4)
c)52.752 or 16.8 
The complete factor of the expression

correct option is D.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is
.
To solve the expression properly we have to take common (2x²). Then we have

The factor is
.

Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
