1. Distribute
5(2n-4)
10n-20
9(n+2)
9n+18
10n-20=9n+18
2. Combine like terms
combine the terms with “n”, and then combine the other numbers.
Hope this helps!
Using Distributive Property:
Combine and get all the terms in left sides and set it equal to zero and solve for m.
(m-5) (m-1) = -3 //Basic step of distribution.
m(m-1) -5(m-1) = -3
m^2 - m - 5m + 5 = -3 //Combine like terms and add 3 on both sides.
m^2 - 6m + 8 = 0 //Factor
m^2 - 4m - 2m + 8 = 0
m(m-4) -2(m -4) = 0
(m-4)(m-2) = 0 //Solve for m.
Got two equations:
1)m - 4 = 0
m = 4
2) m - 2 = 0
m = 2
Solution: m = 4, 2

Answer:
11.45
Step-by-step explanation:
the circumference is 36 so divide it by pie then rounded it to the nearest hundredths place
Answer:
t= -4
Step-by-step explanation:
t/2-16= -18
first add 16 to both sides
t/2-16+16= -18+16
t/2= -2
now multiply both sides by 2
(t/2)2=-2(2)
t= -4
answer check:
substitute the variable for -4
-4/2-16= -18
-4/2= -2
-2-16= -18
-18= -18
