PLZ HELP ME AND SORRY IF THE PHOTO IS BLURRY!?!?

Explanation:

Draw a vertical number line. Make sure 4, 0 and -9 are marked on it.

The distance from 4 to 0 is 4 units, or 4 spaces. Let A = 4.

The distance from 0 to -9 is 9 units, or 9 spaces. Let B = 9.

Add up those distances gives a total of A+B = 4+9 = 13 inches, which is the distance from 4 to -9.

As an alternative, we can subtract and apply absolute value

Let x = 4 and y = -9

|x-y| = |4-(-9)| = |4+9| = |13| = 13

or

|y-x| = |-9-4| = |-13| = 13

When absolute value is used, the order of subtraction doesn't matter.

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

there is nothing below so i cannot
