Answer:
the first one
Step-by-step explanation:
In order to solve this you need to factor the denominator.
x^2 +4x - 12
I see that 12 is a product of 6 and 2 and 4 and 3 and 1 and 12.
I pick the two products that, when added together, give me the 4x term.
Here it's 6 and two I just need to make one of them a negative.
now put them in this form:
(x + 6)(x-2)
In the fraction I see that there is an x-2 in the numerator. This can cancel out with the x-2 in the denominator. Now you have 1/x-6 but remember you can never have a zero in the denominator so x can't equal -6.
And you're done!
To find the height of the triangle you will use the formula to find the area of the triangle and the information provided about the area and the base length.
A= 1/2 bh
558 = 1/2 x 36 x h
558 = 18 x h
To solve for the height divide both sides by 18.
This leaves you with 31 = h.
So, the height is 31 inches.
