Answer:

Step-by-step explanation:
we know that
The perimeter of quadrilateral PQRS is equal to the sum of its four length sides
the formula to calculate the distance between two points is equal to

we have
the vertices P(2,4), Q(2,3), R(-2,-2), and S(-2,3)
step 1
Find the distance PQ
P(2,4), Q(2,3)
substitute in the formula




step 2
Find the distance QR
Q(2,3), R(-2,-2)
substitute in the formula



step 3
Find the distance RS
R(-2,-2), and S(-2,3)
substitute in the formula



step 4
Find the distance PS
P(2,4), S(-2,3)
substitute in the formula



step 5
Find the perimeter

substitute the values



Answer:
$620
Step-by-step explanation:
20 x 10 = 200 + 420 = 620
hope this helped. :)
p.s. can I get brainliest?
Answer:
$0.89/1 the cost is $0.89.
Step-by-step explanation:
cost over lb
13.35/15
unit rate means for 1 so divide 15 by 15 to get 1
what ever u do to the denominator do to the numerator so divide 13.35 by 15
13.35/15 divided by 15/15= 0.89/1
$0.89 for 1 lb
First you would do 5-2.
That would give you 3(x-1)=12
Next, 3 would be distributed into x-1
That would give you 3x-3=12
After that, you add 3 on both sides of the equal sign.
That would give you 3x=15
Finally, divide 3 on both sides and your final answer is:
x=5
If you do a Check, 12 will equal 12.
Hope this helps!!!
