54+x=12+3x
X=21 =number of classes
Total amount she will pay is $75
Answer:
(x + 6)(x + 8)
Step-by-step explanation:
Consider the factors of the constant term (48 ) which sum to give the coefficient of the x- term (14 )
The factors are + 6 and + 8
since 6 × 8 = 48 and 6 + 8 = 14
x² + 14x + 48 = (x + 6)(x + 8) ← in factored form

The r correlation coefficient is usually used in a conjunction with a best-fit line. This means that given a set of data points, we want to find a line which all the points are closest to. Then we measure how close the points are to the line using the r-value, which tells us the relationship between the variables. This correlation coefficient is called linear because the best-fit model we attempt to place is usually a line.
