Answer:
6
Step-by-step explanation:
Factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Factores of 42 are: 1, 2, 3, 6, 7, 14, 21, 42
6 is the greatest common factor.
-10
combine like terms -5x+9=59 subtract 9 from both side and get -5x=50 so x=-10
width = 5k^2
length( 3k^2 +7k +4)
15k^4 +35k^3 +20k^2
The width is the greatest common factor
We can factor 5k^2 out
5k^2( 3k^2 +7k +4)
The length is what is inside the parentheses
-16 = m + 71
Move +71 to the other side. Sign changes from +71 to -71. To get m by itself.
-16-71=m+71-71
-16-71=m
-87=m or m=-87
Answer: -87=m or m=-87
