Answer:

3x^2 +4x-4

Step-by-step explanation:

We know the zeros are  -2 and 2/3

Using the zero product property

(x- -2) (x -2/3) = 0

(x+2) (x-2/3) = 0

We want to write the function, so we need to FOIL

first x*x = x^2

outer: -2/3x

inner: 2x

last: -4/3

Add together

x^2 -2/3x +2x -4/3 =0

x^2 -2/3x+6/3x -4/3 =0

x^2 +4/3x - 4/3 =0

We can multiply by any constant and it will still give us the same zeros

I will multiply by 3 to get rid of the fractions

3(x^2 +4/3x - 4/3) =0*3

3x^2 +4x-4 = 0

Ierofanga [76]

Answer:

Step-by-step explanation:

Draw a triangle and label the sides (picture below):

● the length is 2x+2

● and the width or the height is 6x

The perimeter of a rectangle is the sum of the sides

● P = 2x+2 + 6x + 2x+2 + 6x

Isolate the similar terms

● P = (2x+2x+6x+6x) + (2+2)

● P = 16x + 4

If f(1) = 6 and f(n) = f(n − 1) +3, then f(7) =<br> (1) 10 (2) 24 (3) 15<br> (4) 18
Juliette [100K]

Answer:

24

Step-by-step explanation:

f(n) = f(n − 1) + 3

if n = 7 => f(7) = f(7-1) + 3 = f(6) + 3

if n = 6 => f(6) = f(6-1) + 3 = f(5) + 3

if n = 5 => f(5) = f(5-1) + 3 = f(4) + 3

if n = 4 => f(4) = f(4-1) + 3 = f(3) + 3

if n = 3 => f(3) = f(3-1) + 3 = f(2) + 3

if n = 2 => f(2) = f(2-1) + 3 = f(1) + 3

if f(1) = 6 then f(2) = 9

f(3) = 12

f(4) = 15

f(5) = 18

f(6) = 21

f(7) = 24

Answer:

Choice 'D' (10x + 9) (10x-9) is the correct answer

Step-by-step explanation:

100x^2 - 81

This is a difference of squares...

therefore = (10x + 9) (10x - 9)
