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)
The response variable in the study that Ann has done here can be said to be Time spent exercising.
<h3>What is a response variable?</h3>
This is the name that is used to refer to the dependent variable. This is the variable that is of interest in the study. The goal is to see the changes that occurs in the particular variable based on the actions that another variable would have such as the independent variable.
From this we can see that The response variable in the study that Ann has done here can be said to be Time spent exercising.

The number that is not irrational is 
. The correct option is the second option
<h3>
Irrational numbers </h3>
From the question, we are to determine which of the given options is not irrational
Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q, where p and q are integers.
is a repeating decimal and it can be expressed as a fraction
∴ is not an irrational number. It is a rational number
The other options cannot the expressed as a fraction.
Hence, the number that is not irrational is . The correct option is the second option

Answer:
<h2>She was driving at 40.42 mph on average</h2>
Step-by-step explanation:
In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute
Data
distance= 64 mile
time= 1hr 35min
to covert 1 hr 35 min to hours we have
= 1 + 35/60 (we are converting 35 min to hrs)
= 1+0.583
= 1.583
hence speed= 64/ 1.583
speed= 40.42 mph
She was driving at 40.42 mph on average
