Rosa finds the product of 32 and 96. she rewrites 96 as a sum or difference of two numbers and uses the distributive property. w
Nady [450]

Solution:

We are given with the  two numbers=32 and 96

Product of the given numbers=32*96= 3072

But Rosa rewrites the 96 as a sum or difference of two numbers and uses the distributive property

As we know, the Distributive property is a(b+c)= ab+ac

Now,  32*96 = 32*(100-4) = 3200-128

So, option 'd' is correct

Add the length and width of rectangle A and set equal to the sum of the length and width of rectangle B.
Then solve for d.
Once you know d, substitute it in each length and width to find the actual lengths and widths.

0.7d + 1 + 1.5d - 2 = 2.5 + d + 4 - 1.3d

2.2d - 1 = -0.3d + 6.5

2.5d = 7.5

d = 3

Rectangle A:
Length: 0.7d + 1 = 0.7(3) + 1 = 2.1 + 1 = 3.1
Width: 1.5d - 2 = 1.5(3) - 2 = 4.5 - 2 = 2.5

Rectangle B:
Length: 2.5 + d = 2.5 + 3 = 5.5
Width: 4 - 1.3d = 4 - 1.3(3) = 4 - 3.9 = 0.1
