c
Step-by-step explanation:
Answer:
the answer is 15
Step-by-step explanation:
Given data:
Volume V = 45 π and radius
r = 3 units The formula for the volume of the cylinder is V = B · H
Base of the cylinder is:
B = r² π = 3² π = 9 πFrom the formula V = B · H we get H:H = V / B = 45 π / 9 π = 5 units
H = 5 units
Answer:
Let's solve for x.
4x+2y=345x−6y
Step 1: Add -345x to both sides.
4x+2y+−345x=345x−6y+−345x
−341x+2y=−6y
Step 2: Add -2y to both sides.
−341x+2y+−2y=−6y+−2y
−341x=−8y
Step 3: Divide both sides by -341.
−341x
−341
=
−8y
−341
x=
8
341
y
Step-by-step explanation:
Answer:
30(x+1)/(x+7)
Step-by-step explanation:
This is not a rational expression because denominator has a domain of which it can be undefined.
To rationalize multiply by the reciprocal of the denominator (1/6+1/x+1)
___<u>5___ </u>*(6)(x+1) --> _____<u>30(x+1)_____</u> --><u> 30x+1</u>_ --> <u>30x+1</u>
1/6+1/x+1 *(6)(x+1)--> 6(x+1)/6 + 6(x+1)/(x+1) --> (x+1)+6 --> x+7
Final Answer: 30(x+1)/(x+7)
