If the perimeter of this polygon is 20 in., what is the length of the missing side? A. 2 in.
B. 3in.
C. 4 in.
D. 5 in.

2 inches

Step-by-step explanation:

A. 20

Step-by-step explanation:

Add all the sides up; 5 + 3 + 3 + 7 = 18; then u do 18 + 2 to get the perimeter of 20.

Hope this helps! Brainliest plz?

i think is g(1)=-1.

hope that i can

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
