Heron’s formula: Area = square root 5(5-a)(5-b)(5-c) What is the area of triangle DFG? Round to the nearest whole square unit. 2

timurjin [86]

To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.

Here is an example. If the sides are 3, 4, 5.
It would be:

$A= \sqrt{6(6-3)(6-4)(6-5))}$

The 6 is in the formula because it is the semi-perimeter (half).

Consider this quadratic equation.

soldi70 [24.7K]

Answer:

-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2) (the last choice).

Step-by-step explanation:

Im ignoring the 2^2 in the equation

The equation transforms to

2x^2 - 3x - 5 = 0 (standard form)

So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)
