4x/15 = 60/x
4x^2 = 900
x^2 = 225
x = 15
Step-by-step explanation:
Let (2n +1) be the larger odd number by definition, where n can be any real integer. Then (2n - 1) is the smaller consecutive odd number.
The product of the 2 odd numbers is (2n + 1)(2n - 1) = 4n^2 - 1 = 2(2n^2) - 1. Since n^2 must be an integer, 2(2n^2) - 1 is odd. (Shown)
160/4 = p/6
Cross-multiply the propportion:
160 x 6 = 4p
Divide each side by 4:
p = 40 x 6 = 240 pages
Answer:
y=x² +6
Step-by-step explanation:
This is the only 2nd-degree equation in the group: y = x² + 6. The others are linear equations.
2x + a = b Subtract a from both sides
2x = b - a Divide both sides by 2
x =
