1.The sum of three numbers is twenty. The second number is four times the first and the sum of the first and third is eight. What are the three numbers?

Step-by-step explanation:

4x=12

x=12/4

x=3 answer

y=4*3=12 answer.

z=8-3=5 answer.

proof

3+12+5=20

20=20

3,12,5

Step-by-step explanation:

sum of three numbers = 20

sum of first and third = 8

second number = sum of three - sum of first and third = 20-8=12

second number = 4* first

first = 12/4 = 3

third = 8-3 = 5

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

the answer is 175.4379
