Answer:
3n+5
Step-by-step explanation:
Like terms are the terms that can be added together, in this example, 7 and -2. There aren't any other like terms so if you add them together, the answer would be 3n+5.

Answer:
151
Step-by-step explanation:
Volume of a cone can be found using the equation below
V=π(r^2)(h/3)
<u>divide diameter by two to find the radius</u>: 8/2=4
<u>Plug the values into the equation</u>: V=π(4^2)(9/3)
<u>Simplify</u>
V=π(4^2)(9/3)
V=π(16)(3)
V=150.79
Rounds up to 151

Answer:
25
Step-by-step explanation:
that what i got
Consecutive means in order, so like 1,2,3,4... or 14,15,16,17...
consecutive even means 2,4,6,...
now, first you define some variables
let "a1" be the first positive even integer
well, you could define a2,a3,and a4 to be the next consecutive even integers but you actually dont need to
because the next consecutive even integer is
a1+2
the 3rd is
a1+2+2
and the 4th is
a1+2+2+2=a1+6
now, looking at the problem it states the "third" times the "fourth" is equal to 21 times the "first"
putting it into equation form
(a1+4)* (a1+6)= 21*a1
solve for a1, and then it should be easy to determine the rest of the positive consecutive even integers
