Answer:
xy
2xy
4
Step-by-step explanation:
A factor is a number of term you can factor out of each part of the expression/ or divide it by.
In -24xyz - 12xy + 20xyz
All three parts have xy, so it is a factor
All three don't have 12xz, because -12xy doesn't have z variable for instance.
All three have 2xy.
All three can't factor out 3y, because you can't divide 20 by 3 nicely.
All three can't factor out 4yz, because middle term -12xy doesn't have z.
All three can't factor out 12, because you can't nicely divide 20/12.
All three can factor out 4, because -24, -12, and 20 are all divisible by 4.

Answer:
Step-by-step explanation:
Let the original water level is x.
<u>Use below equation to find its value:</u>
- x + 2.4 + 3 1/2 = 162 + 14.6
- x + 2.4 + 3.5 = 176.6
- x + 5.9 = 176.6
- x = 176.6 - 5.9
- x = 170.7 cm
Answer:
The triangular prism is a better deal because you get 204 in³ for the same price you would pay for 128 in³ with a trapezoidal prism.
Step-by-step explanation:
The trapezoidal prism has volume 32*4=128 cubic inches. The triangular prism has volume 34*6=204 inches. Since the triangular prism is more voluminous, it is the better deal. Hope this helps!

Answer:
20(E)
Step-by-step explanation:
Printing press R, S and T are working together at their respective constant rate.
They can do a job for 4 hours.
Let r, s and t be the time for printing press R, S and T to complete the job alone at their respective constant rate.
Rate of printing press R = 1/r
Rate of printing press S = 1/s
Rate of printing press T = 1/t
Rate = job / time
R + S + T = 4
1/r + 1/s + 1/t = 1/4
S + T = 5
1/s + 1/t = 1/5
Substitute 1/s + 1/t = 1/5 in the equation 1/r + 1/s + 1/t = 1/4
1/r + 1/5 = 1/4
1/r = 1/4 - 1/5
1/r = (5 - 4)/ 20
1/r = 1/20
r = 20 hours
It takes the printing press R 20 hours to complete the job alone
