(4 x 8) + (7 x 8 ) = 11 x 8 = 88
(15 x 1) + (15 x 3) = 15 x 4 = 60
9(2 + 3)
7(5 + 6)
32 + 20 = 4 x (8 + 5)
(2 x 9) + (3 x 9) = 5 x 9 = 45
The GCF in this case is 3. 75 + 18 = 93 93/3 = 31 Rewriting 31 as another sum seems unnecessary, but sure. (30+1) * 3 = 93 = 75 + 18.
(4 x 9) + (5 x 9) = (9 x 9)c= 81
(15 x 1) + (15 x 3) = 15 x 4 = 60
9(2 + 3)
3 (21+5)
11(5 + 6)
5(8 + 5)
7(7 + 9)
9(2 + 3)
7(5 + 6)
The sum is 84 and the GCF is 6
32 + 20 = 4 x (8 + 5)
