1 answer:

3 0

The error Alex made while simplifying the expression 7+(3x 1. 4)+5+2+(5x1. 4) is "he found the perimeter of the figure instead of the area".

<h3>How to find area of an object?</h3>

The area of an object is the product of the length and width of the objects.

Alex added the dimensions of the grid instead of multiplying them.

7+(3x 1. 4)+5+2+(5x1. 4)

For instance,

Area of a rectangle = length × width
Perimeter of a rectangle = 2(length + width)

Therefore, Alex found the perimeter of the figure instead of the area".

In Olongapo City, a bump car ride costs

dimulka [17.4K]

Solve for n in 270=120 + n*10. 120 gives you first 30 minutes and n is the number of additional 10 minutes you ride. In this case you ride for 30+n*10 minutes. n = (270-120)/10 = 15. So the total time is 30+15*10 = 180 minutes. Or three hours!! That’s a lot of bumper cars!!
