Use Pythagorean theorem, C^2 = A^2 + B^2
Where c is the hypotenuse, and b and a are the sides.
Substitute and solve:
To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%
Based on the above calculations, the percent of increase in the amount of iron is 50%

General Formulas and Concepts:
Pre-Alg
- Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
f(x) = -3x^2 + 9x
f(-2) is x = -2
Step 2: Solve
1. Substitute: f(-2) = -3(-2)^2 + 9(-2)
2. Evaluate: f(-2) = -3(4) + 9(-2)
3. Multiply: f(-2) = -12 - 18
4. Add: f(-2) = -30
