Answer:
A. LCM=72 B. GCF=7 C. 7(5+9)
Step-by-step explanation:
A. 8/2=4/2=2 9/3=3 Use the denominators to find the LCM. In this case, the LCM is 72.
B. 35/5=7 63/3=21/3=7 The GCF for these numbers is 7 because it is the only factor that they have in common.
C. 7 x 14=88 Since 5 and 9 don't have common factors, they work perfectly for this problem.
Answer:
7.25
Step-by-step explanation:
![(4a+7b-12c)-(8a-9b+12d)\\4a+7b-12c-8a+9b-12d](https://tex.z-dn.net/?f=%284a%2B7b-12c%29-%288a-9b%2B12d%29%5C%5C4a%2B7b-12c-8a%2B9b-12d)
Negative multiply negative = Positive
Negative multiply positive = negative
![-8a+4a+9b+7b-12c-12d\\-4a+16b-12c-12d](https://tex.z-dn.net/?f=-8a%2B4a%2B9b%2B7b-12c-12d%5C%5C-4a%2B16b-12c-12d)
Thus the answer is -4a + 16b - 12c - 12d.
