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".

Answer:
37/24
Step-by-step explanation:
Since the denomenators must be consistent, both 8 and 12 have the common factor of 24.
the denominator of 8 must be multiplied by 3 to get to 24, but to multiply the denominator you must multiply the numerator by 3 which gives you
15/24
the denominator of 12 must be multiplied by 2 to get 24, so you must multiply 11 by 2 as well to get
22/24
add them together to get 37/24
The length of the third side is 4 7step-by-step the explanation- the perimeter of a triangle is 16 to the square root of 7 feet.
Yo sup??
this is of the form called slope and point... hence
y-11=-4(x+2)
therefore the correct answer is option A
Hope this helps
Answer:
x = 5
Step-by-step explanation:
3x + 2(2x − 1)= 33
simplify
3x + 4x - 2 = 33
7x - 2 = 33
add 2 to both sides
7x - 2 + 2 = 33 + 2
7x = 35
divide both sides by 7
7x/7 = 35/7
x = 5
