The smaller number is 3 more than the larger. four times the larger is the same as 13 minus six times smaller
tatuchka [14]
We will say the smaller number is X and the larger number is Y
The first sentence states y=x+3 and the second sentence states 4y=6x-13
You can use substitution in this to plug in y=x+3 into 4y=6x-13 to get
4(x+3)=6x-13 now move -13 to the other side to get 4x+16=6x then move 4x to the other side to get 16=2x giving you X
X=8
Now plug in X into the equation y=x+3
y=(8)+3 giving you Y
Y=11
Now plug in both X and Y to check
4(11)=6(8)-13
44=35

1. Create an expression, containing at least two variables, that can be factored using the sum of two cubes identity.
podryga [215]
Remember that the sum of tow cubes identity is: a^3+b^3=(a+b)(a^2-ab+b^2)
So, to create our expression<span>, containing at least two variables, that can be factored using the sum of two cubes, we just need to replace </span>a and b with tow monomials with a different variable:
a=x and b=y
Lets replace those values in our identity: 
x^3+y^3

Now that we have our expression, lets factor it using the sum of two cubes identity:
x^3+y^3=(x+y)(x^2-xy+y^2)
To verify if the factored form of our expression (right hand side) is equivalent to the original form (left hand side), we are going to expand the right hand side:
x^3+y^3=(x+y)(x^2-xy+y^2)
x^3+y^3=x^3-x^2y+xy^2+x^2y-xy^2+y^3
x^3+y^3=x^3+x^2y-x^2y+xy^2-xy^2+y^3
x^3+y^3=x^3+y^3

Since both sides of the equation are equal, we can conduce that the factored form of our expression is equivalent to the original expression.
