Solve 5x^2 - 3x + 2 = 11

x =  1.81 or x = - 1.21  both to 3 significant figures

Step-by-step explanation:

First you put 11 on the other side of the equal sign so the equation is equal to 0.

5x^2 - 3x -9 = 0

Then you use the quadratic formula to solve it (picture gives an EXAMPLE)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
