What is the perimeter of a triangle with side lengths of 9, 12, and 4x?

1 answer:

3 0

The answer is 21 + 4x.

You find this answer by adding up all the sides.
9+12+4x= 21+4x ... you don't add 4x because it has a variable that we do not know of the value.

I NEED WORK

vazorg [7]

2)The goal is to isolate the variable and get is down to x<?. This is actually a two step inequality problem. 0.7x - 2 < 5.5 +2 +2 0.7x<7.5 This implies: x<10.714 The way to graph this is to place an open circle of the number 10.714 on the number line indicating this number is not included as a solution to the inequality. Then draw the arrow going left from the open circle indicating all numbers from -∞ to 10.714.
