The correct answer would be B. 22.63 cm.
Answer: Down Below
Step-by-step explanation: Solving for -2x^3 + 15x^2 - 22x - 15(x - 3) = 0
Standard form:
−2x3 + 15x2 − 37x + 45 = 0
Factorization:
−(2x − 9)(x2 − 3x + 5) = 0
Hello! I would love to help!
Let's first define solve. Solve means to get the variable, or unknown, by itself. So, we know that we've solved the equation if we get our variable, x, by itself.
Let's look at the problem like this: What number, minus 1/2, is equal to 4?
To solve this problem, let's reverse the order.
X-1/2=4
Since it is -1/2, let's add 1/2 to each side to cancel the one half out, since -1/2+1/2=0
X-1/2+1/2=4+1/2
Now, we can simplify!
X=4 1/2
That is your answer! X=4 1/2 or as an improper fraction 9/2.

Answer:
(0, -6)
Step-by-step explanation:
Given the following systems of linear equations;
3x - 2y = 12 ...... equation 1
16x - 4y = 24 ........ equation 2
We would solve for the solution using the elimination method;
Multiplying eqn 1 by 2, we have;
2 * (3x - 2y = 12)
6x - 4y = 24
16x - 4y = 24
Subtracting the two equations, we have;
(6x - 16x) + (-4y -[-4y]) = (24 - 24)
-10x - 0 = 0
-10x = 0
x = -0/10 = 0
Next, we would find the value of y;
3x - 2y = 12
3(0) - 2y = 12
0 - 2y = 12
-2y = 12
y = -12/2
y = -6
Check:
3x - 2y = 12
3(0) - 2(-6) = 12
0 - (-12) = 12
12 = 12
