-36i^2 because -12 X 3= -36 and i X i = i^2
Lubov Fominskaja [6]3 years ago

-12i×3i=-12×3×i×i
12×3=36 i×i=i²
So in the case of basic algebra, it's 36i²

If i is √-1 then i² is √-1×√-1 which is -1
36×-1=-36

Find the exact length of the third side
devlian [24]
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.

b= square-root of (c^2)-(a^2)

b= square-root of (9^2)-(2^2)

b= 8.77.... which in the exact form is square root of 77.

PLEASE HELP ME WITH THIS THANKS
stich3 [128]

Answer:

The answer to your question is Volume = 12735.06 cm³

Step-by-step explanation:

Data

a = 11.26 cm

s = 13 cm

h = 29 cm

Formula

V = BH

Process

1.- Calculate the area of the base

Area = B = Pa/2

P = Perimeter

P = 6(13)

P = 78 cm

Area = (78)(11.26)/2

        = 878.28/2

       = 439.14 cm²

2.- Calculate the volume

Volume = BH

             = (439.14)(29)

             = 12735.06 cm³
