Answer:
20(3m-2)
Step-by-step explanation:
In order to factor, you have to look for the greatest common factor, or what the biggest number could the two numbers be divided by.
In this case, both numbers can be divided by 20, and so we put the 20 outside of the parentheses.
This leaves with 3m and -2, which are left inside the parentheses.
Hope this helps :)
There are 18 that are divisible by 5. 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95
now find which of those are divisible by 3 (divide the numbers by three and if its a whole number that works for example 30 divided by 3 is 10 so thats one)
S^2 = one face of a cube
S^2 × 6 = entire Surface Area (SA) of cube
One face = 9^2 = 81 cm^2
SA = 81 × 6 = 486 cm^2
