The answer is 27
Remember that the number inside the lines are always positive so in this case it will be
|-8|+19 which will equal to
8+19=27
Answer:
1/2
D
Step-by-step explanation:
slope =

Same ratio. Both reduce to 
We know that
<span>Of all the rectangles having same area, square has the least perimeter
</span>
area of square=x²
where
x is the length side of the square
A=72 cm²
72=x²
x=√72-----> x=6√2 cm
Perimeter of square=4*x------> 4*(6√2)-----> P=24√2 cm
P=33.94 cm
the answer is
the perimeter is equal to 24√2 cm or 33.94 cm
Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
