Step-by-step explanation:
You add them together
Hope this helps!
No it's positive since if you multiply both sides by -1 you will get 5m=20 & m=4
Another method -5m =-20, divide both sides by -5, you will get the same positive m =4
When multiplying out you get:
x2+4x-3x-12....
so you'd be adding the +4x to the -3x
x2 + x - 12
121 over 121 is a whole number of 1
The area of the square will be 196cm².
<h3>How to calculate the area?</h3>
It should be noted that the perimeter of a square is the addition of all its sides. Therefore, the length of the side will be:
= 56/4
= 14
Therefore, the area of the figure will be:
= 14²
= 14 × 14
= 196cm²
