Find the distance between the pair of points.. (-6, -5), (7, -8)

horrorfan [7]

Answer:

$\sqrt{178}$ units

Step-by-step explanation:

Use the distance formula $d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$ where $d$ is the positive distance between $(x_1,y_1)$ and $(x_2,y_2)$ :

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

$d=\sqrt{(-8-(-5))^2+(7-(-6))^2}$

$d=\sqrt{(-8+5)^2+(7+6)^2}$

$d=\sqrt{(-3)^2+(13)^2}$

$d=\sqrt{9+169}$

$d=\sqrt{178}$

Therefore, the distance between $(-6,-5)$ and $(7,-8)$ is $\sqrt{178}$ units.

Giving brainliest for correct awnser. Factor the expression below.

tresset_1 [31]

Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:

$x^2 + 18x + 81$

$x^2 +3x + 27x + 81$

Group:

$(x^2 +3x) (27x + 81)$

Take out GCF (Greates Common Factor):

x(x + 3) 27(x + 3)

(x + 27) (x + 3)
