Start by distributing the - 1/3 which is the same as dividing the entire parentheses by 3 which results in (3x+10)
Step-by-step explanation:
4) y²-1=48
y²=49
y=±7
option C -7 and 7
5) x²=289
x=±17
-17 and 17
The first (and most typical) way to find distance of two points is by using the distance formula.

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
