Answer:
The expression of the area of rectangle ABCD as simplified polynomial will be:

Hence, the 2nd option is correct.
Step-by-step explanation:
As we know that the area of a rectangle can be obtained by multiplying the length by the width.
i.e.

Given
The length of a rectangle ABCD =
= 
The width of a rectangle =
= 
so the expression of the area of rectangle ABCD as simplified polynomial will be:

![A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cleft%28x%2B5%5Cright%29%5C%3A%2B%5C%3A%5Cleft%283x%5Cright%29%5C%3A%2B%5C%3A%5Cleft%284x-9%5Cright%29%5Cright%5D%5C%3A%5Ctimes%20%5Cleft%5B2x%5Cright%5D)




Therefore, the expression of the area of rectangle ABCD as simplified polynomial will be:

Hence, the 2nd option is correct.
Answer:
x=2
TU:4(2)-1=7
UB: 3
TB: 10
Step-by-step explanation:
4x-1+2x-1=5x
6x-2=5x
6x=5x+2
subtract 5x from both sides
x=2
TU: (4x-1)
4(2)-1
8-1
7
TU:4(2)-1=7
UB: (2x-1)
2(2)-1
4-1
