I will give 30 to who ever will figure this out please helps it’s due in the morning

1. 13x+4        2.   -6x-7      3.  -8x-7      4.   7x+3/x+2     5.  -3        9x2+24x+15/3x+2   6.

Step-by-step explanation:

number 4 is a fraction answer so put 7x+3 at the top x+2 at the bottom

number 6 is a fraction answer so 9x2+24x+15 at the top rest at the bottom

also, 2 is the exponent for number 6

sorry, I didn't do number 7 it's kinda complicated.

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
