Answer:
D. 23/27
Step-by-step explanation:
The good news is, they wrote out all the possible options for you.
There are 27 possibilities in all, so that's our denominator.
They want to know which possibilities have a W in there OR an R comes first. So we'll count up the possibilities that start with R. There are 9.
Then, of the remaining 18, 14 include a W somewhere in there.
9 + 14 = 23 out of 27.
We are not counting the Ws in the possibilities that start with R, because of the OR in the sentence.

Celina says true that each of the following expressions is actually a binomial expression.
<h3>What is binomial?</h3>
The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are the two separate terms.
Celina says that each of the following expressions is actually a binomial in disguise:
a. 5abc - 2a² + 6abc = 11abc - 2a²
The is a binomial expression.
b. 5x³∙2x² - 10x⁴ + 3x⁵ + 3x∙(-2) x⁴ = 7x⁵ - 10x⁴
The is a binomial expression.
c. (t+2)² - 4t = t² + 4
The is a binomial expression.
d. 5(a - 1) - 10(a - 1) + 100(a - 1) = 95a - 95
The is a binomial expression.
e. (2πr - πr² )r - (2πr - πr²)∙2r = -2πr² + πr³
The is a binomial expression.

The Y-Axis is higher on the "+4" equation, so the parabola will look taller.
Answer: 6 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V): π x radius ² x height
Replacing with the values given and solving for v (Volume)
1584 = π x r ² x 14
Solving for r:
1584 / (π x 14) = r²
36.01 = r²
√36.01 = r
6 cm = r
In conclusion, the radius of the cylinder is 6 centimeters.
