Stanley is putting wallpaper strips on his bathroom walls that have a total area of 450 square feet. Each strip of wall paper covers between 20 and 24 square feet. Estimate how many strips of wallpaper Stanley will need. Explain how you solved this problem.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

the answer to the expression is 83

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
