A school playground is a 25m by 40 m rectangle. The school increases the width to 40m and increases the length so that the original rectangle and the new one are similar. By how much does the perimeter increase? F 30m
G 60m
H 200m
J 225m

astronomers is your final answer! : )

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
