What is the perimeter of the triangle ?

132 cm

Step-by-step explanation:

Perimeter of triangle = a + b + c

a = 33 cm

b = 55 cm

c =?

a + b = 33 + 55 = 88 cm

c = 88 ÷ 2 = 44

Perimeter of triangle = 88 + 44 = 132 cm

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
