Answer:
Step-by-step explanation:
try to do the quadractic formula. i forgot how to do this
Area =
sum of the length of the parallel sides
multiplied by the distance between them
divided by two
area =

area =

area =

area = 12
add the units:
area = 12
I believe it is 2.5 if you need me to explain I can
Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.
Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).

First, we need to find 33% of $402. (132.66)
Now since it's 33% less than before, we need to add how much the price was reduced by.
402+132.66= 534.66
The original price was $534.66
