Answer:
x = -10 or x = -3
Step-by-step explanation:
Here, the given equation is
The given equation can be solved by the method of SPLITTING THE MIDDLE TERM
Split 13 in such a way that sum of the terms = 13
and product of the terms = 30
So, the given equation becomes 
Here, 10x+ 3x = 13x and 10 x 3 = 30
Now, simplifying the equation,
⇒ either (x+ 10) = 0 ,or (x+ 3) = 0
⇒ x = -10 or x = -3
Answer:
4/5 or 0.8
Step-by-step explanation:
x + 4 = 15
- 4 -4
x = 11
You would subtract 4 because you need to isolate the x to get the value of x. You would subtract it to both sides because whatever you do on one side, you have to do it to the other side.
If you would like to find the function that gives the profit Betty makes by selling a number of glasses of lemonade, you can find this using the following steps:
p ... profit
g ... glasses of lemonade
f(g) = p = g * $1 - $50
The correct result would be f(g)<span> = g * $1 - $50.</span>
The answer is 37 years old.
I = -425x² + 45500x -650000
I = 450000
-425x² + 45500x -650000 = 450000
-425x² + 45500x - 650000 - 450000 = 0
-425x² + 45500x - 1100000 = 0
Divide all factors by 25:
- 17x² + 1820x - 44000 = 0
This is quadratic equation (ax² + bx + c = 0)
Since, the youngest age is needed, the correct answer is x = 37
