(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
<h3>Using the above property and the fact that 28 and 35 are multiples of 7 to get the equivalent expression</h3>
The given expression is 
Since 28 = 7 times 4 and 35 = 7 times 5
Thus,

Thus,
