Multiple Choice

what is the formula for finding the hypotnuse?

• a²⁺b²=c²
• a+b=c
• a-b=c
• c-a=c

Multiple Choice

How is the distance formula correctly written:

• $d\ =\ \sqrt{\left(y_{1\ }-\ y_2\right)^2\ -\left(x_{2\ }-\ x_1\right)^2}\$

• $d\ =\ \sqrt{\left(y_{1\ }-\ y\ _2\right)^2\ +\ \left(x_{2\ }-\ x_1\right)}^2\$

• $d\ =\ \sqrt{\left(x_{2\ }-\ x_1\right)^2\ +\ \left(y_{2_{\ }}-\ y_1\ \right)^2}$

• d = $\sqrt{\left(x\right)^2-\ \left(y\right)^2}$
