582 cause its right :)
Step-by-step explanation:
It is true that To "Derive" means to get an equation from a specific information.
<u>Explanation:</u>
If we have an equation, we can easily answer various questions. The equation is derived by the data given, observations, results and assumptions. We also need to consider the law and theories while deriving an equation. While deriving an equation, the dependent and independent variables are arranged accordingly.
<u>Example</u> - To derive the formula of a quadratic equation.
- To derive something that is not an equation means to come to a conclusion from the results of the data obtained.
Answer: -2 3/4, -2.2, 2.8, 3 1/8
Step-by-step explanation:
The greatest common factor and factoring by grouping of the following is;
- 3m
- 2a
- 8xy
- 5mn
- 3(r + t)²
- z²(m + n)⁴
<h3>Greatest common factor</h3>
The greatest common factor is the largest positive integer or polynomial that is a divisor of several different numbers. For instance, the greatest common divisor of 66, 30 and 18 is 6.
9m³, 3m², 15m
= 3m
4a², 6a, 2a³
= 2a
16xy³, 24x²y², 8x²y
= 8xy
10m²n², 25mn³, 50m²n
= 5mn
6m(r + t)², 3p(r + t)⁴
= 3(r + t)²
7z²(m + n)⁴, 9z³(m + n)^5
= z²(m + n)⁴
