28 + 35 = (4 x 7) + (5 x 7) = 9 x 7 = 63
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84
9(2 + 3)
The difference.
7(5 + 6)
32 + 20 = 4 x (8 + 5)
12(6 + 5)
First, we find the greatest common factor (GCF) of 15 and 81, which is 3. The sum of 15 and 81 is 96. Therefore, the product of the GCF and the sum is 3 multiplied by 96, which equals 288. Thus, the final answer is 288.
Factor the sum of terms as product of the GCC and a sum of 10t+15
40 + 44 = (4 x 10) + (4 x 11) = 4 x 21 = 84
3 (21+5)
11(5 + 6)
5(8 + 5)
9(2 + 3)
.
9(2 + 3)
7(7 + 9)
The GCF of 75 and 90 is 15.
