HURRY PLEASEEEEE The measure of segment AB with a(-4,-9) and B(4, -3) is

solmaris [256]

Answer: 10

Step-by-step explanation:

using $d = \sqrt{(x_{1}-x_{2} )^{2} +(y_{1}- y_{2} )^{2} }$ when $P_{1} =(x_{1} ,y_{1} )$ and $P_{2} = (x_{2}, y_{2})$

so $d = \sqrt{((-4)-4)^{2}+((-9)-(-3))^{2} }$

$d = \sqrt{(-4-4)^{2}+(-9+3)^{2} }$

$d = \sqrt{(-8)^{2}+(-6)^{2} }$

$d = \sqrt{64+36}$

$d= \sqrt{100}$

$d = 10$

Select the expression that has a quitiont greater than 1. Explain your reasoning.

iren2701 [21]

The answer is 3 1/8 divided by 2 2/5. What I did was turn all of them into improper fractions then divided (which is basically cross-multiply). By doing so, you would have 14/3 divided by 21/4 which equals 0.8888888 or 8/9 in fraction form, 25/8 divided by 12/5 which equals 1.30208333 or 1 29/96, 13/7 divided by 7/3 which equals 0.79591836 or 39/49, and 23/4 divided by 59/8 which equals 0.77966101 or 46/59
