Answer:
A
Step-by-step explanation:
4x+3y=2
3y = - 4x + 2
y = - 4x / 3 + 2/3
You add all of it up and divide by how many numbers are.... so the answer would be D- 56
Answer:

Step-by-step explanation:
Answer: x= pi
Step-by-step explanation:
The answer is 3 + √5 and 3 - √5.
This is quadratic equation: x²
- 6x +
4 = 0
The general quadratic equation is ax² +
bx +
c = 0
Our equation can be rewritten: 1x² + (-6)x + 4 = 0
So, in our equation we have: a = 1, b = -6, c = 4
Now, x can be calculated using the formula:
