23 over 21 is the right answer
23
----
21
Answer:
1. if you are solving using the quadratic formula. the answer is in the first picture.
2. if you are looking to completing the square the answer is in the second picture.
Step-by-step explanation:
The circle: x = 4 y = 0.5
The square: x = 3.5 y = 1.5
The triangle: x = 0 y = 2.5
C=2πr
The C stands for circumference
the π is Pi (3.14)
and r is the radius (length of half a circle)
Since the sides are 10 ft you multiply that by 2 to get the length of both sides which gives you 20 feet.
Then to find the circle, since both are half circles. You can just do the normal circumference equation and you will end up with the same answer.
For example in this problem: this problem gives you the diameter but you need the radius of the circle. C=2(π)(1.5)
C=9.42 < this is the circumference of the circle.
Then you add the sides of the table which are 20 feet.
So the final answer is 29.42 feet.
Hello!
All you have to is isolate the X variable :)
X + 25 = 45
X = 45 - 25
X = 20
I hope this helps :))
