The discriminant of equation ax^2+bx+c = 0 is b^2-4ac.

Here b = 12, a = -4, c = -9 so discriminatn is

b^2-4ac = 12^2-4(-4)(-9) = 144 - 144 = 0.

The discrimant is 0. This tells us that there is only 1 x-intercept for this quadratic

A triangular flag has an area of 493 square meters and a height of 17 meters. What is the length of the base
ahrayia [7]

Answer:

\frac{984}{17} or around 57.88

Step-by-step explanation:

We can find the base length by using the formula for the area of a triangle.

A=\frac{bh}{2}

Plug in the values that we know, the area and the height, and solve for b.

493=\frac{17b}{2}

984=17b

b=\frac{984}{17}So the base is [tex]\frac{984}{17} or about 57.88 if you round to the nearest hundredth.
