There’s this app called Socratic that you can use. It’s like this one but it’s a little different
Answer:
the equation would be: y=(x-4)(x+2)
The college student took 13 courses of 3 credit hours.
Step-by-step explanation:
Given,
Total credits = 59
Total courses = 18
Let,
Number of 3 credit hour courses = x
Number of 4 credit hour courses = y
According to given statement;
x+y=18 Eqn 1
3x+4y=59 Eqn 2
We will eliminate y to find the number of 3 credit hour courses, therefore,
Multiplying Eqn 1 by 4

Subtracting Eqn 2 from Eqn 3

The college student took 13 courses of 3 credit hours.

We have to put the numbers in order..
(121,122,125, 126,132),M,(135,136,136,138,140)
minimum : (smallest number) = 121
Q1 : 125
Q2 (median) : (132 + 135) / 2 = 267/2 = 133.5
Q3 : 136
maximum : (largest number) = 140
