the function c= 75x + 2400 gives the cost in dollars for a small company to manufacture x widgets. the function R = 225x - x^2 gives the revenue in dollars for selling x widgets. how many widgets should the company produce so that the cost and revenue are equal?

i think it is 70

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
