Answer:
B because it is parallel perpendicular
$3.75 => because if you carry down the decimal autimatically then you subtract like normal and bam. theres the answer.
Well you could round that to 290*7 (closer but harder to calculate)
wich equals 2040
Or...
You could round it to the hunderdth's place 300 (further but easier to calculate)
which equals 2100
Answer:
14 ft
Step-by-step explanation:
The perimeter of the pen Christina first decide to make is;
Perimeter = L + L+ W + W
= 6 ft + 6 ft + 11 ft + 11 ft
=34 feet
Now she wants the width to be only 3 ft and the perimeter to be the same.
34 ft = L + L + 3 ft + 3 ft
34 ft = 2L + 6 ft
subtract 6 ft from both sides of the equation to give you;
28 ft = 2L
Divide both sides of the equation by 2 to give you;
L = 14 ft
This is the correct answer for the system of equations
