Answer:
Option B is correct
Step-by-step explanation:
Doug is x years old, so Byron is x+3 years old. The product of their ages would then be x times x+3:
x(x+3) = 40
x2 + 3x = 40
x2 + 3x + 40 = 0
Now, factor the equation:
(x+8)(x-5) = 0
Then, solve for both values of x:
x+8 = 0
x = -8
x-5 = 0
x = 5
As no one can have a negative age, we simply disregard x=-8 as invalid. Therefore, Doug is 5 years old & Byron must be 5+3 - or 8 years old.

Answer:
it is the best deal cause i said
Step-by-step explanation:
The range is all y values in the scatter plot
Since i can't see the scatter plot you'll have to answer this.. but remember
Range is all y values
In this question, the given value is
And we have to find the value of sin theta and tan theta where theta is in first quadrant .
And in first quadrant, all are positive .
Now we use the formula, which is
And tan theta is the ratio of sin theta and cos theta, that is
So the correct option is B .
