Steve has a fenced garden in the shape of a rectangle. Its area is 317.8 square feet. The width of the yard is 14 feet. What is the length of the fence?

22.7 feet

Step-by-step explanation:

Area of a rectangle=Length X Width

If:

Substituting into the formula for area

317.8 = Length X 14

Divide both sides of the equation by 14

Length =22.7 feet

The length of the fence is 22.7 feet.

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
