What is the surface area of a triangular pyramid if each face has an area of 30 mm2?

2 answers:

7 0

The answer must be $120\quad m{ m }^{ 2 }$ since the triangular pyramid has 4 faces and each has an area of 30 $m{ m }^{ 2 }$ we should multiply that by 4 , so :

$4\cdot 30\quad m{ m }^{ 2 }=\quad 120\quad m{ m }^{ 2 }$

Use the discriminant to determine the nature of the roots of the following equation.

kvv77 [185]

Discussion

The discriminate is b^2 - 4*a*c

The general equation for a quadratic is ax^2 + bx + c

In this equation's case

a = 1

b= -5

c = - 3

Solve

(-5)^2 - 4*(1)*(-3)

25 - (-12)

25 + 12

Note

Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
