Hannah wants to rewrite 18+12 using the greatest common factor and the distributive property. Which expression should she write?
1 answer:
Answer:
6(3+2)
Step-by-step explanation:
Distributive property:
ab + ac = a(b+c)
where a = greatest common factor (GCF)
GCF of each factor
18 = 2×3×3
12 = 2×2×3
GCF of 18 and 12 = 2×3
= 6
Therefore,
18 + 12 = 6(3) + 6(2)
= 6(3+2)
Where,
6 = a
3 = b
2 = c
ab + ac = a(b+c)

+21. +21
6x=126
×=21
21y=75
Divide 21 from 75
Y= 3.6
Answer:
x = 11
Step-by-step explanation:
2(x - 5) = 12 ← divide both sides by 2
x - 5 = 6 ( add 5 to both sides )
x = 11
