yes 4x7=28
1x28.....2x14....4x7
All the terms have 4x4 as a factor Then, 4x7 + 32x5 + 24x4 = 4x4(x3 + 8x + 6)
2x2 is 4. 4x7 is 28. 28x5 is 140.
Commutative i think dont blame me if wrong
2x7=14double = 4x7= 28
28
4x7=28 2(4x7)=2x28=56

4x7=28(4x7=2x28=56
-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)
You can use the product from 4x7 to find the product of 8x7 by doubling the answer to 4x7. The product of 4x7 is 28 and the product of 8x7 is 56 (28 doubled is also 56).
the answer for 4x76 is 304
Double it.
