If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.
If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
The answer for this question is "y = -5/3 and x = 8/3"

Answer: (c * d)(x) =
4x^3 + 18x^2 - 10x</h3>
Work Shown:
I'm assuming the dot means multiplication. If so, then,
(c * d)(x) = c(x)*d(x)
(c * d)(x) = [ c(x) ] * [ d(x) ]
(c * d)(x) = (4x-2)(x^2+5x) .... substitution
(c * d)(x) = 4x(x^2+5x) - 2(x^2+5x) ... distribute
(c * d)(x) = 4x(x^2)+4x(5x) - 2(x^2)-2(5x) ... distribute again
(c * d)(x) = 4x^3 + 20x^2 - 2x^2 - 10x
(c * d)(x) = 4x^3 + 18x^2 - 10x
Answer:

Step-by-step explanation:
To find which systems of equation represents the situation, we can break down the key information and create two variables:
<u>Variables:</u>
Let
= number of sundaes sold.
Let
= number of banana splits sold.
<u>Given information:</u>
Sundae: 
Banana Splits: 
8 more sundaes sold than banana splits. This can be expressed by
.
Total sold was
. This can be expressed as
.
∴ The systems of equation that expresses this situation are
and
.
Hope this helps :)
