Hi there!
We are looking for the circumference of the school field. When we assume that the field is a rectangle, we can use the following formula for finding its circumference.
Circumference = 2 × length + 2 × width
Plug in the length and width from the question.
Circumference = 2 × 50 + 2 × 10
Multiply first (remember: PEMDAS).
Cirxumference = 100 + 20
And finally add.
Circumference = 120.
Hence, the total length of the fence will be 120 meters.
~ Hope this helps you!
Take you the common factors. those are 2 and x. So if you divided 2x^2 by 2x you end with only one x. and if you divided 4x by 2x you end with 2. The final answer should look like 2x(x+2)=2x^2+4x
Answer:
What is the question?
Step-by-step explanation:
Step-by-step explanation:
the solutions for a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -4
c = k
x = (4 ± sqrt(16 - 4k))/2 = 2 ± sqrt(4 - k)
x1 = 2 + sqrt(4 - k)
x2 = 2 - sqrt (4 - k)
x1 = 2 + x2
2 + sqrt(4 - k) = 2 + 2 - sqrt(4 - k)
2×sqrt(4 - k) = 2
sqrt(4 - k) = 1
4 - k = 1
k = 4 - 1 = 3
x1 = 3
x2 = 1
Answer:
-7pi √3
Step-by-step explanation:
Treating pi as a variable, the simplified value can be written as;
-7pi √3
This can be obtained from using the following simple methodology;
pi(√3 -8 √3)
= pi (-7 √3)
