Enter your answer as a decimal. Round ONLY your final answer to the nearest tenth.

In order to solve this this problem, you first need to know the formula of a triangle which is b×h/2 (First measure the bottom of the triangle and find how long that is and then measure the height of the triangle and do the same thing. Then multiply both of those measurements together and with your answer divide it by two.) And of course your answer should be a decimal, so if you need help with entering your answer as a decimal or rounding to the nearest tenth or any other problem that I can hopefully answer, you can send me a message on brainy. Good luck!

Answer:
option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.
Step-by-step explanation:
we have
This is the equation of a vertical parabola open upward (the leading coefficient is positive)
The vertex represent a minimum
The vertex is the point (0,-225)
The axis of symmetry is x=0 (y-axis)
Find the x-intercepts (values of x when the value of y is equal to zero)
For y=0
square root both sides
therefore
The graph has zeroes at x = 15 an x = -15 and it opens upward.
