1. what is the phythaforean theorem? 2.what do we use it for? 1.what is the distance formula ? 2.what do we use it for?

phythaforean theorem:

1 . The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

2.  Find the square root to find the accurate length of the hypotenuse.

distance formula:

1. The distance formula is used to determine the distance, d, between two points.

distance = speed × time

Formula- d= √x2-x1)²+(y2-y1)²

2. It's used for :

-Finding the perimeter of polygons

-Finding the area of rectangles

-Finding the equation of a circle

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
