✯Hello✯
↪ There is a quadratic formula that needs to be used. 4ac and b^2 are a part of this formula
↪ First we need to work out the Values for A and B and C
A = 1
B = 5
C= 4
↪ now we can substitute this into what the equation is asking. (5)^2-4(1)(4)=9
↪ The answer is 9
↪ I hope this helps you :)

Answer:
Step-by-step explanation:
<u>Since the points have same x- coordinate of -7, the distance is the difference in y - coordinates:</u>
- d = -3 - (-9) = -3 + 9 = 6
Correct choice is C
Relatively prime means having no factors in common.
I will start by checking if they have the factor "3" in common: it's easy to check: the sum of its digit needs to be divisible by 3:
<span>a. 72 And 115
7+2=9
1+1+5=7
not true that both are divisible by 3
b. 120 And 835
1+2=3
8+3+5=16
</span>
<span><span>not true that both are divisible by 3
but, they're both divisible by 5! (0 or 5 at the end)
not relatively prime
</span> c. 201 And 735
2+1=3
7+3+5=15
both are divisible by 3!
d. 303 And 1041
3+3=6
1+4+1=6
both divisible by 3
the answer is a)
