2 part question. Part A. Which side is parallel to side HK? A. Side LM B. Side MN C. Side NP or D. Side PL
Part B. What is the scale factor of the dialation? A. 1/3 B. 1/2 C. 2 or D. 3
Need help on both questions.

Part A. B - Side MN

Side MN is directly parallel to side HK because, as shown by the graph, it is directly across from side HK.

Part B. B - 1/2

If you look at the width or length of the larger rectangle (the original), and compare that to the smaller, you can see that both the length and width of the larger rectangle are double the smaller rectangle.

Hope this helps!! :)

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
