7 times a number is 18 less than the square of that number. Find the positive solution.
Arte-miy333 [17]
So 7 x = x2 -18 so you get the quadratic x^2 -7x -18 and then get 2 x -9= -18 and 2 + -9 = -7 so you get (x + 2) ( x - 9) so the positive solution would be x-9 = 0 so x= 9. Hope this helps :)

The length of one leg of a right triangle is 24 feet and the length of the hypotenuse is 40 ft what is the length of the other l
Rama09 [41]
To solve for the other leg, you need to use Pythagorean theory.

The theory states that C^2 = A^2 + B^2

In your case, you have to solve for B.
C = 40 (hypotenuse)   A = 24 (leg 1)

The formula rewritten for B is b= \sqrt{c^{2}-a^{2} }

Now, you can solve.

b= \sqrt{c^{2}-a^{2} }&#10;&#10;b= \sqrt{40^{2}-24^2 }&#10;&#10;b = \sqrt{1600 - 576}&#10;&#10;b = \sqrt{1024}&#10;&#10;b = 32

Therefore, B = 32.

So the second leg is 32 feet.
