Determine the distance between -1 and -7

6 because you count from -1 to -7 and it can’t be a negative number because it’s impossible to count down to find the distance which means it always has to be positive to find the distance. in conclusion the answer is 6. you can also do -1- -7 which changes the double subtraction to addition and takes the negative away from -7 so -1+7=6!

Since you are making a equationnumber = x2(x + 7) = 3x    is your equationdistribute the 2 to both x and 72(x) = 2x2(7) = 142x + 14 = 3xsimplify, move the x to one side, and the number to the other2x + 14 = 3x2x(-3x) + 14 (-14) = 3x (-3x) (-14)2x - 3x = -14-x = - 14isolate the x, divide -1 from both sides-x/-1 = -14/-1x = -14/-1x = 14    is your answerhope this
