The hypotenuse of a triangle is one foot more than twice the length of the shorter leg. The longer leg is seven feet longer than
Serhud [2]
Start by calling the shortest side s. We then know that the longer leg (call it l) is 7 feet longer i.e. l=s+7. We also know that the hypotenuse, h is 1 foot more than twice the short leg i.e. h=2s+1. We now have 3 unknowns but only 2 equations to solve them. Luckily we know this is a right triangle so we can use the Pythagorean Theorem as our third equation:
a^{2}+b^{2}=c^{2}
Substituting known values:
s^{2}+(s+7)^{2}=(2s+1)^{2}
This is now an equation in one variable and can be solved algebraically for s. Back-substitution can then be used for the other sides.

Solve for x in the equation x² - 4x - 9 = 29.
yawa3891 [41]

Answer: First option.


Step-by-step explanation:

 1. To solve this problem you can applly the quadratic formula, which is shown below:

 x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}

2. The quadratic  equation is:

x^{2}-4x-9-29=0\\x^{2}-4x-38=0

3. Then:

a=1

b=-4

c=-38

4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

x=\frac{-(-4)+/-\sqrt{(-4)^{2}-4(1)(-38)}}{2(1)}

x=2±√42
