If you factor the expression of part A, you will get the expression of part B
the reason is that the perimeter of a rectangle is equal to 2(l+w)
so in the factorization number 2 will be multiplied by the rest of the expression
good luck
4.35 & 4.34. Just try to find two numbers that can add up to 8.69. There are many different answers such as 2.69 and 6, 3.98 and 4.71, etc.
For first pound it is = $2.41
For next six, = 0.41 * 6 = $2.46
Remaining = 7.99 - (2.41 + 2.46) = 7.99 - 4.87 = 3.12
Now, additional pounds = 3.12 / 0.39 = 8
Total weight = 1 + 6 + 8 = 15
In short, Your Answer would be 15 pounds
Hope this helps!
