Answer:

144 cm²

Step-by-step explanation:

A prism's surface has 2 triangles & 3 rectangles.

In both the triangles , length of :

Perpendicular = 4 cm

Base = 6 cm

So , Area of both triangles = $2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2$

In the 3 rectangles ,

Length = 8 cm

Width = 5 cm

So , Area of the rectangles = $3( Length * Width) = 3(8 * 5) = 120 cm^2$

Hence the total surface area of the prism is = 120 + 24 =144 cm²

choosing a blue marble does not represent the complement event of choosing a red marble because 2/5 ≠ 4/5.

Step-by-step explanation:

The total number of marbles ⇒ 2 blue + 1 red + 2 purple = 5 marbles.

What are the solutions to this problem? (use the quadratic formula and i)<br><br> -2x^2+5x-11=0

Sever21 [200]

Step-by-step explanation:

The quadratic formula is:

$x = \frac{-b \pm\sqrt{b^2-4ac} }{2a}\\$

A, in this case, is -2.

B is 5

C is -11

x = $\frac{-5 \pm\sqrt{5^2-4(-2)(-11)} }{2(-2)}$

x = $\frac{-5\pm\sqrt{25 -88} }{-4}\\$

x = $\frac{-5\pm\sqrt{-63}}{-4}$

x = $\frac{-5+i\sqrt{63} }{-4}$ and $\frac{-5-i\sqrt{63} }{-4}$

We can break up the fraction to make it easier on our eyes

x = $\frac{5}{4}\pm\frac{i\sqrt{63} }{4}$

$\frac{\sqrt{63} }{4}$ ≈1.9843

x = $1.25 + 1.9843i\\1.25 - 1.9843i$
