The equation would be (3+√-16)(6-√-64)
A negative square root can not be a real number, meaning that we have to use the imaginary number.
(3+4i)(6-8i)
How to multiply imaginary numbers...
Treat this like an equation looking like (x-a)(y-b)
Use FOIL
(3+4i)(6-8i)
= 18-24i+24i-32i²
= 18-32i² (i²= -1 because i= √-1)
= 18- (-32)
= 18 + 32
= 50
Answer:
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Step-by-step explanation:
We will write the equation to represent this scenario.
Let x be the number of people who went for movies.
Then the price of ticket for x people will be: 6.25x
They spent $12 on refreshments and a total of $30.75 so the equation will be:

solving the equation will give us total number of people
So,

Hence,
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Im pretty sure its 180 hope this helps
Answer:
f(-1) = 3
General Formulas and Concepts;
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 9(3)ˣ
x = -1
<u>Step 2: Solve</u>
- Substitute: f(-1) = 9(3)⁻¹
- Evaluate: f(-1) = 9(1/3)
- Multiply: f(-1) = 9/3
- Divide: f(-1) = 3
Answer: The required probability is 0.32.
Step-by-step explanation:
Since we have given that
Probability of winning team A over B = 0.7
Probability of losing team A over B = 0.3
Number of matches = 7"
So, using the "Binomial distribution" :
We get that

Hence, the required probability is 0.32.
