Answer:

n = -2

Step-by-step explanation:

-5(6n+6) = 30

-30n-30 = 30

-30n = 30+30

-30n = 60

-n = 60/30

-n = 2

n = -2

A LOT OF POINTS pls help and answer correctly if not I will report ty asap !
Solnce55 [7]

Answer:

hey

Step-by-step explanation:

to calculate perimeter, you require length,breadth

since points are given,find distance between points using distance formulae

<h2>root over (x2-x1)² +(y2-y1)²</h2>

______________________

<h3>Point H =(6,7)</h3><h3>Point I=(-6,-9)</h3><h3>Point J=(-10,-6)</h3><h3>Point G=2,10)</h3>

Now find distance between HI and IJ

HI gives the distance - length of rectangle

IJ gives the distance - breadth of rectangle

use the formulae ,2(length+breadth) to get perimeter

______________________

HI= root over 144+256= root 400

HI=20

IJ= root over 16+9= root 25

IJ=5

PERIMETER =2(20+5)

2×25

=50
