It is always possible for the product of a rational number and irrational number to result in a rational value.
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
Answer:
d : 4, 1, -2.
Step-by-step explanation:
There's no need for a calculator in my opinion because we can use the rational root theorem which states that the equations of this form:

Have rational roots, than the roots are of the form: 
Rewriting the equation we have:
