Answer:
The perimeter of the second square is 36 inches
Step-by-step explanation:
Given
Represent the sides of the squares with S1 and S2.
So:
--- Scale factor
--- perimeter of the first
Required
Calculate P2, the perimeter of the second
Represent the ratios of the perimeter:
Substitute 12 for P1
Equate both scale factors
Convert to fraction
Cross multiply
Answer:
1.Isolate y
3y=10-8x
y=10/3-8/3x
2.Put in correct format (y=mx+b)
y=-8/3x+10/3
y= -8/3x+10/3
slope is -8/3 and y-intercept occurs in 10/3 or 3.333
I got that x equals -3.809523 (repeating)

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
