Answer:
Step-by-step explanation:
There are two consecutive positive even integers such that the square of the first is 364 more than five times a second. What are the two numbers?
Two consecutive year positive integers are represented by
x and x + 1
First integer = x
Second integer = y
There are two consecutive positive even integers such that the square of the first is 364 more than five times a second.
This is represented mathematically as:
x² = 364 + 5(x + 1)
x² = 364 + 5x + 5
x² -5x -5 - 364
x² - 5x - 369

Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n
