Helpp I'm lost I know it's easy but not for me

11

Step-by-step explanation:

Using the Pythagorean theorem we can solve this problem.

Pythagoras' theorem= hyp^2-side^2

There are 2 sides in this right-angled triangle. Let's name one side "side a" and the other "side b". Side b is what we'll be finding for.

Hypotenuse= 12

Side a= 5

Side b=?

But in this case we already know the value of the hypotenuse so we have to find for a side.

side^2= hyp^2-side^2

Side^2= 12^2-5^2

Side b= 144-25

Side b= 119

Side b= √119

Side b= 11

Therefore Side b= 11

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
