It might take about 200 and something because its very useful
B.
Since he had to subtract 7 to get to -3, you would have to find the expression that would yield that answer.
Hope this helps!
Answer:
x^2 + 5n = 4mx
=> x^2 - 4mx + 5n = 0
D=0 (since one root then roots are equal)
b^2-4ac = 0
(-4m)^2 - 4(1)(5n) = 0
16m^2 - 20n = 0
16m^2 = 20n
8m^2 = 10n
4m^2 = 5n
hope it helps.......
n, n + 2, n + 4 - three consecutive even integers
n + 2 = 2(n + 4) - 6 |use distributive property
n + 2 = (2)(n) + (2)(4) - 6
n + 2 = 2n + 8 - 6
n + 2 = 2n + 2 |subtract 2 from both sides
n = 2n |subtract 2n from both sides
-n = 0
n = 0
n + 2 = 0 + 2 = 2
n + 4 = 0 + 4 = 4
Answer: 0, 2, 4.
Answer:
18π ≈ 56.5 meters
Step-by-step explanation:
The length of the arc of a circle is given by the formula ...
s = rθ . . . . where r is the radius, and θ is the central angle in radians
<h3>Application</h3>
You are given the values of r and θ, so you only need to put them into the formula and simplify.
s = (27 m)(2π/3) = 18π m
The length of the arc is 18π meters, about 56.5 meters.
