Answer:
Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, 
, already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:
<h2>Your answer is 1/14!</h2>
Answer:
unit rate is 6.66 miles per hour .
Step-by-step explanation:
here's the solution :-
distance covered by mya = 10 miles
time taken = 1.5 hours
=》
=》
=》
hence, unit rate = 6.66 miles per hour.
2y(x3+9x-10x2-45) not much to be taken as a common factor

Answer:
(13 x + 6) (x - 2)
Step-by-step explanation:
Factor the following:
13 x^2 - 20 x - 12
Factor the quadratic 13 x^2 - 20 x - 12. The coefficient of x^2 is 13 and the constant term is -12. The product of 13 and -12 is -156. The factors of -156 which sum to -20 are 6 and -26. So 13 x^2 - 20 x - 12 = 13 x^2 - 26 x + 6 x - 12 = x (13 x + 6) - 2 (13 x + 6):
x (13 x + 6) - 2 (13 x + 6)
Factor 13 x + 6 from x (13 x + 6) - 2 (13 x + 6):
Answer: (13 x + 6) (x - 2)
