Answer:
2(x+1)= 2x+2.
Step-by-step explanation:
Because, there is a on infront of x so you do 2x1=2 so 2x+2 because 2x1=2

I might be wrong, but hopefully that helped! :)
Answer:
One mass's kinetic energy is 4 times the other.
Step-by-step explanation:
The formula for kinetic energy is 
Where
KE is the kinetic energy
m is the mass
v is the velocity
- Now, let mass of the first be m (second is identical so mass of 2nd is m as well)
- Let velocity of the first one be v. Since 2nd one is travelling twice as fast, its velocity will be 2v
<u>KE of 1st mass is:</u>
<u />
<u>KE of 2nd mass is:</u>
Hence, the kinetic energy of the 2nd mass is 4 times the first.
First, you've got to figure out the value of the radius so divide the diameter by two. Then, you'll want to find the area of the base or pi times radius squared.
(3.14x3^2)x9=V
After doing the math your answer comes out to 254.34 cubic feet or feet^3
Answer:
144
Step-by-step explanation:
<u>Data:</u>
<em>Emily's age</em> : 46 years old
<u>Find Colin's age</u>
<em>Colin's age</em>: 11 years older than Emily
Emily's age + 11
46 + 11 = 57 years old
<u>Find Dan's age</u>
<em>Dan's age</em>: 5 years younger than Emily
Emily's age - 5
46 - 5 = 41 years old
<u>Find their combined ages</u>
<em>Combined ages</em>: Emily's age + Colin's age + Dan's age
<em>Combined ages </em>= 46 + 57 + 41
Total = 144
Therefore, the total of their combined ages is 144.
