Answer:

4x^2 + 8x + 4

4(x^2 + 2x + 1) - remove GCF of 4

4(x + 1)(x + 1) - factor

4(x + 1)^2 - collect like terms

Step-by-step explanation:

Then also expand it out by distributing:

21x^3 + 35x²

Form 1:

21x^3 + 35x² - unfactored

Form 2:

7x²(3x + 5) - factored with GCF of 7x² brought to the front

Update:

You could also multiply two binomials and make a quadratic.

Example:

(7x + 2)(3x + 5)

7x(3x + 5) + 2(3x + 5)

= 21x² + 35x + 6x + 10

= 21x² + 41x + 10

Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +
skad [1K]

With the information given, we deduce that the parabola is

y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

y=x^2-6x+5

And to shift down a function, you subtract the shift from the equation: the equation becomes

y=x^2-6x+5-2=x^2-6x+3

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

|x+2|\mapsto -|x+2|\mapsto -|x+2|+3

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

y(0)=3

For the other function, we have

y(0)=-|2|+3=-2+3=1

In Erin's career on the basketball team, she made 7 out of every 10 free throws Last season, she
Crazy boy [7]

Answer: 42

For this situation we will use a ratio to show how many free throws Erin will make. Using the ratio 7:10 represents that Erin will make 7 out of every 10 free throws. You want to know how many free throws  she will make if she attempts 60 free throws.

Using ratios we will be able to find how many free throws she will make if she attempts 60.

7:10

14:20

21:30

28:40

35:50

42:60

Basically we kept multiply the right side of the ratio which is 10 by 2 until we were at 60 free throws.

Erin will make 42 free throws if she attempts 60 free throws.
