David is making a snack mix from dried fruit and can spend $32. Raisins cost $4per pound and cranberries cost $6 per pound. He wants to write and graph anequation to find three combinations of the number of pounds of raisins andcranberries he can buy. He wrote steps to solve the problem on note cards but they got mixed up. HelpDavid by writing the steps in the correct order.

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

or

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
