General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 4x
f(-7) is x = -7
<u>Step 2: Solve</u>
- Substitute: f(-7) = (-7)² + 4(-7)
- Evaluate: f(-7) = 49 + 4(-7)
- Multiply: f(-7) = 49 - 28
- Subtract: f(-7) = 21
Hello!
I believe the answer is dividend.
Look at it like this..
10 / 5 = 2
^ ^
dividend divisor ^ quotient.
Hope this helps! ☺♥
The answer to the question is m = 2
22, each side length is about 15.6. when you use Pythagorean theorem you can get it more accurate. 242 + 242=c^2 which is the side lengths squared anyways. you add to get 484=c^2 so square root and you get 22 units as you r answer!
hope it helps!
