The answer is -6+x=8. x is the unknown number. To find the distance, try to use a number line. And the answer to the expression is 14. To get from -6 to 0, you add 6. Then from 0 to 8, you add 8. 8+6=14
The answer is 16 units An easy way to find the perimeter is remembering the formula of a+b+c. So in this case, you count how many units each line of the triangle it covers. 4+6+6= 16
