Area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?

Mathematics

Answer:

x + 9

Step-by-step explanation:

Area = 2x^2 + 18x

Width = 2x

Length = ?

The relationship between these quantities is;

Area = Length * Width

Length = Area / Width

Length = (2x^2 + 18x) / 2x

Using long division;

2x\sqrt{2x^{2}  + 18x}

This leads to;

length = x + 9

Checking;

Area = Length * Width

Area = (x + 9) * 2x

Area = 2x^2 + 18x ; This is correct!

Answer:

200 yd²

Step-by-step explanation:

A = 17 yd

B  = 15 yd

C = 2 yd

D = 8 yd

b) Area of rectangle = length * width

 \sf Area \ of \ 2 \ triangle = 2*  \dfrac{1}{2}* base * height = base* height\\\\

Area of right triangular prism = Areas of two triangle +  area of the upper rectangle + area of middle rectangle + area of below rectangle

          = 8 * 15 +  17 * 2 + 15 *2 + 8*2

          = 120 + 34 + 30 + 16

          = 200 yd²
