Sebastian said that if a number is a perfect square. then the number is even. Provide two examples that show that the statement is false.

Below!

You can take 25 as one example and 49 as the second example.

Let's factorize.

Hence, the statement is not true.

Hoped this helped.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
