because they are all grouped together
191=4m-25
191+25=4m
216=4m
216/4=m

4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
Answer:
since -5 and -5 are the same number, they are on the same y axis so the only distance we need to calculate is between the X coordinates
so when looking for distance you can not have a negative what |-3|+|9| is looking for is the distance from 0 on the X axis since distance can't be negative, (you go 3 miles away from your house in one direction, vs 3 miles in the opposite both ways is positive, even with opposite directions same with axis, it doesnt matter which way, only the number.) you need the absolute value of -3 to get the distance from the 0 on the x axis
short version: distance is positive and its adding the distances from the x axis to get distance from each other
