Answer:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from to
and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:
We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:
Now we can divide both sides of the inequality by 2 and we got:
And that's different from the claim of the student that:
The error of the student is that he/she changes the sign of the inequality from to
and that's not possible since we don't multiply both sides of the equation by -1
A square has four sides which all have the same length.
So if we call the length of each side of the square 'a'
The sum of length of all the sides (the perimeter) will be ,
a + a + a + a = 4a
Now let's equal this to the perimeter to find the length of each side 'a'
So the length of each side of the square is 2 cm
To find area of a square we multiply the length of its two sides
So,
is the area of the square,
