Alex simplified the expression 7+(3x 1. 4)+5+2+(5x1. 4) to find the area of the figure on the grid.
fredd [130]

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".

Solve each system using elimination. 3x+3y=27 x-3y=-11
Natalija [7]

Answer:

x=4

y=10

Step-by-step explanation:

3x +3y = 27

x - 3y = -11 (add these up so 3y will be eliminated and you'll have x only)

4x = 16

now let's eliminate x (you can put 4 instead of x though)

3x + 3y = 27

-3/ x -3y= -11 (multiple the the 2nd equation with -3 to eliminate x )

3x + 3y =27

-3x + 3y =33

6y = 60
