12x^3 +2x^2-30x = 8
2x( 6x^2 +x -15) = 8
so 2x= 8, x=4
(2x) ( 2x-3) ( 3x+5) = 8
2x-3 = 8
2x= 11
x= 5.5
3x+5=8
3x= 3
x=1
Answer:
5 Laps
Step-by-step explanation:
The question says that she runs the same distance everyday. This shows us that...
2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles
We can turn laps into the variable L and miles into the variable M to create an equation
2 L + 6 M = 4 L + 2 M
We can start by subtracting 2 M from both sides to get:
2 L + 4 M = 4 L
Now, we can subtract 2 L from both sides
4 M = 2 L
This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.
Now, we can break down either side of the equation. Let's break down
2 L + 6 M
First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:
2 L + 3 L
Now, we can simplify this :
5 L
Now we know that she ran 5 laps on saturday.
Hope this Helps!!! :)
Let me know in the comments if this answer was perfect or if I should change anything!!!
Answer:
if there are answer choices i would put the closest one to 16
A rhombus would answer your question. Hope this helped sorry if im wrong.
