Answer:
y = - 9, y = 3
Step-by-step explanation:
Calculate distance d using the distance formula
d = 
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (10, y)
d = 
= 
Given distance between points is 10, then
= 10 ( square both sides )
64 + (y + 3)² = 100 ( subtract 64 from both sides )
(y + 3)² = 36 ( take the square root of both sides )
y + 3 = ±
= ± 6 ( subtract 3 from both sides )
y = - 3 ± 6 , thus
y = - 3 - 6 = - 9
y = - 3 + 6 = 3

You dived by the bottom fraction and once again. dived by 12 because ft to inches 12 and you know the order of numbers hope this helps!
Answer:
Perimeter of the rectangle=16 x
Step-by-step explanation:
Step 1: Determine the dimensions of the rectangle
Width=x
Length=7 x
But;
Step 2: Determine the perimeter of the rectangle
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=unknown
W=x
L=7 x
replacing;
2(x+7 x)=2 x+14 x
16 x
Perimeter of the rectangle=16 x
