Answer:
Step-by-step explanation:
7/10 divided by 21/30 is 1
Our goal is to isolate n. In order to do this, we must first get rid of the 15 on the left side of the equation.
To achieve this result, we must do the inverse of the operation on both sides of the equation. In other words, subtract 15 from both sides.
8n + 15 - 15 = 25 - 15
8n = 10
Now we must get rid of the 8, by again doing the inverse of the operation. Since 8 is multiplying n, we must divide it into both sides.
8n / 8 = 10 / 8
n = 1.25
Hopefully, this helps!
If we know that Laura's canvas is square, and one side is 22cm,
area of a square is l*w, with a special case of l=w
the area will be
A= l*w=22*22=484cm^2
also, Asquare is=l^2
