To solve for the quadratic equation 9x² = 4, we need to recall that the difference between two square can be expressed as the product of their sum and difference or (a² - b²) = (a + b)(a - b).
Thus, we have
9x² = 4
9x² - 4 = 0
(3x)² - (2)² = 0
(3x + 2)(3x - 2) = 0
We now have two linear equations:
3x + 2 = 0 | 3x - 2 = 0
3x = -2 | 3x = 2
x = -2/3 | x = 2/3
Thus, x = +2/3 and -2/3.<span>

I'm sorry I'm you can try to see if calculater soup can help you with this problem
Answer:
D
Step-by-step explanation:
"The slope of AB is different than the slope of BC" the slope are on the same straight line, so this is incorrect! It doesn't matter which portion of the line you look at, the slope will always be the same.
I think the answer is 89 degrees.
Let us assume the number of CDs your friend has = n
Then
Number of CDs that you have = n + 11
It is already given that the number of CDs you have = 30
Then
n + 11 = 30
n = 30 - 11
= 19
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the fourth option or option "D". I hope that the answer has actually come to your desired help.
