3/4x4/9 least
then 7/7x4/9
then 1 2/3x4/9
Greatest is 2x4/9

Answer:
Step-by-step explanation:
I will ASSUME you mean y = 3x² at x = 2
The derivative of an equation is the slope the curve at any given point
y' = 6x
so our line slope at x = 2 is 6(2) = 12
at x = 2, y = 3(2²) = 12
so (2, 12) is a point on the line (the point of tangency)
plugging into our slope equation
y = 12x + b
12 = 12(2) + b
b = -12
So the equation of the line tangent to y = 3x² at x = 2 is
y = 12x - 12

Answer: (pr + 1)(q + 1)</h3>
===============================================
Work Shown:
Use the factor by grouping method to get the following.
pqr + pr + q + 1
(pqr + pr) + (q + 1)
pr(q + 1) + 1(q + 1)
(pr + 1)(q + 1)
We can use the FOIL rule, distribution, or the box method to expand out (pr+1)(q+1) to get the original expression again. This helps confirm the answer.
Answer:
30=2r+r
r=5
Step-by-step explanation:
30=2r+r would be the answer for the first question because the red line, 30, is equal to the line 2r and r.
r=7.5 because 30=2r+r (combine like terms)➡️ 15=3r (divide both sides by 3)➡️ 5=r
