I belive it might be (-1.291502622)
Or if you want to simplfy it it can be turned into (-1.29)
Answer: c
Step-by-step explanation:
bc
To answer this question we need to use subtraction.
we need to make the denominators the same.
In order to make them the same we need to find the least common multiple, of 8 and 5.
The least common multiple(the smallest shared value of the two numbers) is 40.
Next we divide our old denominator 5 by 40, which gives us 8, we multiply 8 by the numerator 2, which gives us 16. So now we have 16/20. We have to do the same to the other side. 8÷40 = 5. 5 x 3 = 15. Now we have 15/20.
Now we have a brand new equation, 16/40 - 15/40. The answer is 1/40.
In a fraction the answer is 1/40, so Karen rides her bike further.
In decimal form the answer is 0.025.
I hope this helps!

Answer:
Step-by-step explanation:
pool tables are rectanglar
Perimeter = 2L + 2W = 2(L+W) ---->>> Perimeter/2 = L + W =
Perimeter/2 - W = L
Area = L×W
Two equations and two unknowns and L is substituted into the area equation
---->> Area = (Perimeter/2 - W) x W
Area = (Perimeter x W)/2 - W² solve for W
Area = 36 and Perimeter = 26
36 ft² = (26)( W)/2 ft - W² ft²
36 ft² = 13W ft - W² ft²
W² - 13W + 36 = 0 quadratic equation factor solve for W
(W - 4)(W - 9) = 0
There are two roots
W - 4 = 0 and W - 9 = 0
W = 4 and 9 W = 9 it doesn't make sense needs to be < L
Perimeter/2 - W = L
L = 26/2 - W
= 13 - 4
L = 9 ft and W = 4 ft
