Which congruency statement is true?

For congruency the related sides need to be similar, which means they letters need to be in the correct order.

AB would be EF, BC would be FG and AC would be EG

This would make the correct answer BC ≅ FG

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
