What is boxed is what you put in your stat plot in your calculator (graphing). To find the y intercept you use the value function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 1) and enter 0. Yo find the x intercept you use the zero function on your calculator (if you have a Ti-84 it’s 2nd-> trace-> 2 and follow the instructions it asks). Hope this helps!

Answer:

Factorized

$=(2x-8)(x-3)$

Roots : 4 , 3

Step-by-step explanation:

If it is to factorize :

$2x^2 - 14x + 24 = 2x^2 -6x-8x +24$

$=2x(x-3)-8(x-3)\\=(2x-8)(x-3)$

If it is to solve for x :

$2x^2 -1 4x + 24 = 0\\(2x-8)(x-3)=0\\2x - 8 = 0 \ , \ x - 3 = 0\\2x = 8 \ , \ x = 3\\x = 4 , 3$

Mrs. Nally's swimming pool is 10 feet by 6 feet. She paves the area around it with a sidewalk x feet wide, using 80 square feet

andrew11 [14]

Answer:

The sidewalk is 2 feet wide

Step-by-step explanation:

The area of the sidewalk is given as 80 square feet

The length and width of pool

including side walks will be;

10 + 2x and 6 + 2x

To get the area of the side walk

That will be area of total minus area of the pool

That will be ;

(10 + 2x)(6 + 2x) - 10(6) = 80

60 + 12x + 20x + 4x^2 - 60 = 80

4x^2 + 32x -80 = 0

x^2 + 8x -20

x^2 + 10x - 2x - 20 = 0

x(x + 10) -2(x + 10) = 0

(x-2)(x + 10) = 0

x = 2 or -10

since width cannot be negative;

The sidewalk is 2 feet wide
