I really only need help with part C

Answer:

part A: 72

part B=7

part C=7(5+9)

Step-by-step explanation:

A=the lowest common multiple found in both the 9 and 8 times table. 8s=8 16 24 32 40 48 56 64 72

9s=9 18 27 36 45 54 63 72

B=7 because 35=5×7 and if we break down 63,it

would be 9×7 or 3×3×7

C=7(5+9) because if we expand the brackets it would

be 7×5+7×9=35+63

Hope it helps?

The lowest common factor of 8 and 9 is 72, the greatest common factor of 35 and 63 is 7, and the expression (35 + 63) can be written as 7(5 + 9).and this can be determined by using the arithmetic operations.

A)

Given :

Numbers - 8 and 9

The lowest common factor of 8 and 9 is:

8  ---  8, 16, 24, 32, 40, 48, 56, 64, 72

9  ---  9, 18, 27, 36, 45, 54, 63, 72

So, the lowest common factor of 8 and 9 is 72.

B)

Given :

Numbers --  35 and 63

The greatest common factor of 35 and 63 is:

35 = 5 [tex]\times[/tex] 7

63 = 3 [tex]\times[/tex] 3 [tex]\times[/tex] 7

So, the greatest common factor of 35 and 63 is 7.

C)

Given :

Expression --  35 + 63

35 + 63 = 7(5 + 9)

             = 7 [tex]\times[/tex] 5 + 7 [tex]\times[/tex] 9

             = 35 + 63

So, the expression (35 + 63) can be written as 7(5 + 9).
