Giving away 50 points to correct i need to find the missing measurement. round answer to nearest tenth. you! : )

The figure seems like its a parallelogram.

In a parallelogram :
Opposite sides are equal and
Opposite angles are equal
Hence, The side opposite to 9in. is equal to 9in. and the side opposite to 10in. is equal to 10in.

Area of the figure =b×h
= 8×10
=80in.sq.

Area = b x h = 8 in. x 10 in. = 80 in.

Perimeter = 2 x l + 2 x w = 2 x 9 + 2 x 10 = 38 in.

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

i wish i could you, i have no idea how to answer this
