The equation y=3x2 - 24x+ 45 is in standard form. Write the equation in vertex form. A. y=3(x-4)2 - 3
B. y=3(x-24)2 + 45
C. y=3(x-8)2 + 15
D. y=(x– 8)2 + 15

A. y = 3(x -4)^2 -3

Step-by-step explanation:

y = 3x^2 - 24x + 45

Use the form ax^2 + bx + c

whereas a = 3, b = -24, c =45

Consider the vertex form of a parabola

a(x + d)^2 + e

Since d = b/2a = -24/2(3) = -4

And e = c - (b)^2/4a = 45 - (-24)^2/4(3) = 45 - 48 = -3

So y = a(x + d)^2 + e

y = 3(x -4)^2 -3

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
