Answer:
3.375 miles
Step-by-step explanation:
Each day Maria walks 0.75 miles, so if she walks for 4.5 days, then 0.75*4.5= 3.375 miles.
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.
<h3><u>The value of the unknown number is equal to 1.</u></h3>
6(x + 2) = 20x - 2
Distributive property.
6x + 12 = 20x - 2
Subtract 6x from both sides.
12 = 14x - 2
Add 2 to both sides.
14 = 14x
Divide both sides by 14.
x = 1
