1. a kite in the shape of a rhombus has diagonals that are 25 in long and 15 in long. what is the area of the kite?

2. the seat of a bench is in the shape of a trapezoid with the bases of 6 feet and 5 feet and a height of 1.5 feet. what is the area of the seat?

x= 149. 24+7=31. 180-31=149

step-by-step explanation:

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

answer: i think one of the answer is $150 and $300?
