Ineed with these questions
1: which orderly paired names the location of the library
2: which is the distance from the park to the post office

1 (-7,-5)

2 10 units

from what i can see, library is at (-7,-5)

park is at (6,5) and post office is at (6,-5)

both the park and post office are 5 units away from the x axis - therefore the distance between the two is 10 units

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
