14n + 21

Just distribute the 7 to the 2n and the 3.

7(2n + 3)

(7 * 2n) + (7 * 3)

14n + 21

Find slope for 3y=-4x+6 please help asap :)

Answer: the slope would be -4/3 and the y intercept is 2

Step-by-step explanation: you would have to divide both sides by 3 to get y by itself. that leaves you with -4/3x + 2

24 cm ,18cm ,c We are looking for c

Ierofanga [76]

Step-by-step explanation:

we can find the value of c by Pythagoras theorem

according to Pythagoras theorem

h² = a² + b²

where

h = hypotenuse (i.e. longest side of a right angled triangle)

a = side

b = base

so, we have to find h or hypotenuse here

h² = (24)² + (18)²

h = 576 + 324 = 900

h² = √900 = 30

c = 30

therefore, value of c is 30.

Hope this answer helps you dear!

Using the following picture which side is the hypotenuse?

mylen [45]

Hi!

A hypotenuse is the longest leg in a right triangle.

A right triangle is a triangle that has one 90 degree angle.

The hypotenuse is always directly across from the right angle.

In pictures, right angles are represented by a square.

Therefore, the side with the hypotenuse is side 3, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.
