Answer:
36 is 257% of 14.
Step-by-step explanation:
36/14 = 2.57,
so 36 is 257% of 14.
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
18 inches * 96 = 1728. 1728 / 12 = 144 feet^2. If you need me to explain better let me know.
You can solve the by dividing the change in y by the change in x. the answer should be D
