Answer:
13
Step-by-step explanation:
You are given the function
To find the value of the function f(x) at point x=a, you have to substitute a instead of x into the function expression.
In your case, you have to evaluate f(x) when x=10. Substitute 10 instead of x into the function expression:
x^2 y^2(x+y)(x^2 - xy + y^2)
x^2 y^2(x^3 + y^3)
(x+y)(x^2 - xy +y^2)
2(3m+4n+2)
In fact 2×3m=6m;
2×4n=8n;
2×2=4
cross-section
It means that if you cut through a prism, on either side you would see the same 2d shape.
