The error Alex made is that he found the perimeter of the figure instead of the area.

<h3>Area and perimeter of shapes</h3>

Given the expressions

7+(3x 1.4)+5+2+(5x 14)

He used the expression to simplify the grid

The expression simplified shows that Alex added all the measures of the sides of the grid instead of taking the product of the length and width

Note that the operation Alex performed is the perimeter of the figure instead of the area hence the error Alex made is that he found the perimeter of the figure instead of the area.

For a weekly car rental, a car rental company charges customers a flat fee of $100 plus
zlopas [31]

The way you typed out this sentence was a bit confusing but I think you were saying...

For a weekly car rental, a car rental company charges customers a flat fee of $100 +  and charges 10 cents for every mile traveled. write an equation for the amount of a weekly rental car that travels 15 miles (Please let me know if I am wrong)

The equation would be

10+10 +10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10+ 10 = 150 cents

so they would be charging $1.50

Hoped this helped!

Have a great day/night! :)
