(4x-3y)^2(4x-3y)
=(16x^2-24xy+9y^2)(4x-3y)
=64x^3-96x^2y+36xy^2-48x^2y+72xy^2-27y^3
=64x^2-144x^2y+108xy^2-27y^3

<u><em>The question in English is</em></u>
On a 32-meter roll of fabric, it cuts an eighth of the total. How many meters of fabric are left in a roll?

Step-by-step explanation:
defining variables:

the cost of the t shirt and the cost of jeans, denoted by any variable you want.
I'll use x and y since they are the most common variables (x = shirt y = jeans)
Equation
4 shirts + 5 jeans = 160 dollars
4x + 5y = 160 (the cost of 4 shirts + the cost of 5 jeans is $160)
the cost of 2 shirts + 6 jeans = $150
2x + 6y = 150
L=s+4 bc lisa is 4 and we don't know who old is Sammy..
