Hello from MrBillDoesMath!
Answer: 215
Discussion:
Let's start by rewriting the monomial as
215 x^18 y ^3 z^21
Now..
x^ 18 = (x^6)^3
y^3 = (y )^3
z^21 = (z^7)^3
So those terms are already cubes! The only remaining candidate is the number 215, which is not a cube.
Thank you,
MrB

Question 1 answer: The first and last option.
Question 1 explanation: 2(4x + 2) is 4x = 12 = 2 = 14 x 2 = 28 and 8x + 4 is 8 x 4 = 32 + 4 = 36 which is 8 more than 28 then, 3x = 9 + 2 + 3 x 2 = 28.
2(4x + 2) = 28 and 8x + 4 equals 36 which is 8 more and they're both equivalent to 2(3x + 2 + x) because 2(3x = 2 = x) equals 28.
The percent increase is 150 percent
There are four sets of numbers with 8 as their greatest common factor:
12 and 24
16 and 24
4 and 16 and
16 and 32
Answer:1209
Step-by-step explanation: 36+78 gives you 114, 114+475 gives you 589 then 589+620 brings you to the final answer 1209.
