4(x+1) is the only one equal to 0
It is a nice linear equation. Remember y=mx+b
b is the y intercept you'll see
m is the slope rise over run
I don't like giving answers away but I am ready to help!
Answer:
x = 63°
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
x + 94° + 23° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: x + 117° = 180°
- Subtract 117° on both sides: x = 63°
The product of a number (we will call it x) and 13 is 13*x. Or 13x
