Answer:
C
Step-by-step explanation:
We can use the factored form of the quadratic equation, given by:

Where <em>a</em> is the leading coefficient and <em>p</em> and <em>q</em> are the zeros.
We have zeros <em>x</em> = -2 and <em>x</em> = 3. So, let <em>p</em> = -2 and <em>q</em> = 3:

Next, we are given that our <em>y-</em>intercept is (0, -30).
In other words, when <em>x</em> = 0, <em>y</em> = -30. So:

Solve for <em>a:</em>

Hence, our factored equation is:

For the standard form, expand:

Our answer is C.
Area of triangle = (1/2)*base*height
20.335 = (1/2)*base*8.3
2*20.335 = base*8.3
(2*20.335) / 8.3 = base Use your calculator.
4.9 = base
base = 4.9cm
Answer:
46
Step-by-step explanation:
81 divided by 9 is 9. Therefore it takes 9 miles a gallon. Divide 414 by 9 to get 46 gallons for 414 miles
24365x = 16820
x = 16820/24365
x(rounded to the nearest tenth) = 0.70
