ANSWER
(5r^2 - 6)(2r - 5)
EXPLANATION
Factor by grouping
(10r^3 - 25r^2) + (-12r + 30)
Factor a GCF
5r^2 (2r - 5) -6 (2r - 5)
Combine groups
(5r^2 - 6)(2r - 5)
CHECK
Use FOIL
First: 5r^2*2r = 10r^3
Outside: 5r^2*-5 = -25r^2
Inside: -6*2r = -12r
Last: -6*-5 = 30
Answer:
-2.23
Step-by-step explanation:
Prime factors are multiplying numbers that cannot be divided into smaller numbers.
Let's break down 92.
Divide 92 by 2.
2 x 46.
We can still break this down.
Divide 46 by 2.
2 x 2 x 23.
This is your prime factorization of 92.

Answer:
<h2>Volume = 153938.0 cm³</h2>
Step-by-step explanation:
Volume of a cylinder = πr²h
where
r is the radius
h is the height
From the question
h = 10 cm
diameter = 140cm
We can find the radius using the formula
radius = 70 cm
Substitute the values into the above formula and solve
That's
V = (70)²(10)π
= 4900(10)π
= 49000π
= 153938.0400
We have the final answer as
<h3>Volume = 153938.0 cm³</h3>
Hope this helps you
