Check circled solution(s) ->
(4m-4)^2
<span>= (4m)^2 - 2.4m.4 + 4^2 </span>
<span>= 16m^2 - 32m + 16</span>
It <span> looks like the first thing you have to find is their GCF, ya reckon ?</span>
The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56 .
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64 .
The common factors are 1, 2, 4, and 8 .
The greatest one is 8 .
56/8 = 7
64/8 = 8
56 plus 64 = (8 times 7) plus (8 times 8)
<span>56 plus 64 = </span>8 times (7 plus 8)<span> <== that's the answer</span>
Check it out:
<span>56 plus 64 = </span>120
<span>8 times (7 plus 8) = 8 times 15 = </span><span>120</span>
It is more than 400 because mental maths give you 454 subtract each digit with one other eg. 6-2 ; 7-2 ; 9-5 gives 454
