Hello!
You solve this algebraically
4n - 9 = -9
Add 9 to both sides
4n = 0
Divide both sides by 4
n = 0
The answer is 0
Hope this helps!
Answer: x*3 -6=12
Explanation: I assume you wanted that put into an equation
length of big square

length of small square

difference between length of two square
=5.2-3.5
=1.7
I have included a picture. In the picture you will find the work and final answer.

Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
[Standard Form] 5x + 5y = 35
<u>Step 2: Rewrite</u>
<em>Find slope-intercept form.</em>
- Subtract 5x on both sides: 5y = -5x + 35
- Divide 5 on both sides: y = -x + 7
