Sqrt(16) = 4 because 4^2 = 16 ;
Then, 4 - 5.5 = -1.5 ;
Step 1. Distribute sum groups
x(x^2 - 3xy + 2y^2) +y(x^2 - 3xy + 2y^2)
Step 2. Distribute
x^3 - 3x^2y + 2xy^2 + y(x^2 - 3xy + 2y^2)
Step 3. Distribute
x^3 - 3x^2y + 2xy^2 + yx^2 - 3y^2x + 2y^3
Step 4. Collect like terms
x^3 + (-3x^2y + x^2y) + (2xy^2) + 2y^3
Step 5. Simplify
Answer: x^3 - 2x^2y - xy^2 + 2y^3
Answer:
The answer is C (78.0215)
Step-by-step explanation:
In math when you see the term product it means to multiple.
Let
x-----> the first <span>positive integer
x+1---> </span>the second positive integer
x+2---> the third positive integer
we know that
x*(x+1)=10+4*(x+2)
x²+x=10+4x+8
x²+x=18+4x
x²-3x-18=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=6
so
the numbers are
x=6
x+1=7
x+2=8
the answer isthe numbers are6 7 and 8
