Its Dr. Appiah’s patients’ ages vary less than do Dr. Singh’s patients’ ages and <span>Dr. Cantwell’s patients’ ages and Dr. Singh’s patients’ ages vary about the same amount.</span>
Answer: A and B
<u>Step-by-step explanation:</u>
Here is Pascal's Triangle:
Row 1 (x + y)⁰ 1
Row 2 (x + y)¹ 1 1
Row 3 (x + y)² 1 2 1
Row 4 (x + y)³ 1 3 3 1
Row 5 (x + y)⁴ 1 4 6 4 1
∵
Row n (x + y)ⁿ⁻¹ 1 (sum of 2 digits above) 1
C and D are false. A and B are the only correct answers
Answer: 12n-10= -58
+10. +10 (add to both sides)
12n. = -48
÷12. ÷12 (isolate variable)
n. = -4
We can actually see that the statements that are true are:
A. x = 1 is a solution.
C. x = –1 is a solution.
<h3>What is rational equation?</h3>
Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.
We can see then that:

It's clear that: x ≠ 0 and x ≠ -6.
Looking for the LCM of the left hand side, we will have:

So, we will see that left hand side and right hand side are equal.





or

So, we can see that options A and C are correct.
