Need help ASAP!! Which of the following lists of side lengths represents a right triangle?

A.) 4, 5, 9
B.) 5, 12, 13
C.) 8, 15, 19
D.) 7, 12, 16

Option B

Step-by-step explanation:

Use the Pythagorean Theorem.

For Option A:

It is not a right triangle.

For Option B:

Option B's side lengths can be used as a right triangle.

Hope this helps.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
