Answer:

4x^2 + 12x + 9

Step-by-step explanation:

(2x + 3)^2

it is in the form of (a + b)^2

(a + b)^2 = a^2 + 2*a*b + b^2

(2x + 3)^2

(2x)^2 + 2*2x*3 + (3)^2

4x^2 + 12x + 9

What is the parent function for the following<br><br> f(x) = (x-2) (x-1)
Taya2010 [7]

Answer:

The parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

Step-by-step explanation:

Here, f(x) = (x-2) (x-1)

Now, parent function of a given function is the function, which is PRODUCT OF ALL IT S FACTORS.

Now, here, f(x) has two factors ( x- 2) and ( x-1)

So, the parent function p(x) of f(x) is given as the product of both the factors.

So, we get:

P(x)  = (x-2) (x-1) \\=  x( x-1) -2(x-1)\\=x^2 - x -2x + 2\\= x^2- 3 x + 2\\\implies P(x) = x^2- 3 x + 2

Hence, here the parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

Amy used a total of 7 1/4 gallons of gas while driving her car. Each hour she was driving, she used 5/6 gallons of gas. What was
nika2105 [10]

Answer:  8  7/10  hours

whole part = 8

fractional part = 7/10

========================================================

Work Shown:

x = number of hours driving

(5/6)x = total number of gallons of gas used

(5/6)x = 7 & 1/4

(5/6)x = 7 + 1/4

(5/6)x = 28/4 + 1/4

(5/6)x = 29/4

x = (29/4)*(6/5)

x = (29*6)/(4*5)

x = 174/20

x = 87/10

x = (80+7)/10

x = 80/10 + 7/10

x = 8 + 7/10

x = 8 & 7/10

This is the same as writing 8  7/10

Amy drove 8 full hours, plus an additional 7/10 of an hour.

That mixed number converts to the decimal value 8.7
