The logical step is to <u>factorize the left side of the equation</u>, which becomes:
Then, you can take the square root on both sides.
Not asked, but good to understand the procedure regardless.
Answer:
equation B is linear. A linear equation will not contain exponents.
Step-by-step explanation:
This is a combination problem. The approach to this is by using the nCr method, where n is the number of total objects and r is the number of success. For example, if you want to get 3 red out of the total 4, then that would be 4C3. That means,
4C3 = 4!/3!(4 - 3)! = 4 ways
If you want to get 2 green out of the total 6, then that would be 6C2. That means,
6C2 = 6!/2!(6-2)! = 15 ways
Therefore, there are a total of 4+15 = <em>19 ways</em>.

Answer:
z = - 24
Step-by-step explanation:
Given
- 0.4(0.5z + 4) = 3.2 ( divide both sides by the multiplier - 0.4 )
0.5z + 4 = - 8 ( subtract 4 from both sides )
0.5z = - 12 ( divide both sides by 0.5 )
z = - 24
