Answer:
2m
Step-by-step explanation:
For m, I look for the greatest power of m that is in all of the expressions. Since the first has m^2, the second has m, and the third has m^4, the greatest power of m that is in all expressions is m.
For the number, I look for the greatest factor of 8, 4, and 10. A trick would be to look at the smallest number since the greatest common factor can only be less than or equal to the smallest number. So looking at 4, the factors are 1,2,4. 4 is not a common factor since it does not divide into 10, but 2 is so 2 is the greatest common numerical factor.
Combine 2 and m to get 2m.
Let N be no. of nickles. Then N($.05)+3N($.10)+2N($.25)=$3.40.
Or
4 nickels = $0.20
12 dimes = $1.20
8 Quarters = $2.00
Total = $3.40
Answer:
(x−5y)(9x+8)
Step-by-step explanation:
9x^2−45yx+8x−40y
Do the grouping 9x^2−45yx+8x−40y=(9x^2−45yx)+(8x−40y), and factor out 9x in the first and 8 in the second group.
9x(x−5y)+8(x−5y)
Factor out common term x−5y by using distributive property.
(x−5y)(9x+8)
Answer:
x = -10
Step-by-step explanation:
first you multiply both sides by -3
x + 7 = -3
then you subtract 7 from both sides
x = -10
