Iwill give you a brealeant

you don't have to to put 1,2 but you need to solve it to do 3

6 3/4

Step-by-step explanation:

 1. Use proportion:

8:4.5=24:x

8x=24*4.5

x=3*4.5

x=13.5

2. Use proportion

8:4.5=4:x

x8=18

x=18/8

x=9/4

x=2.25

3. For 24 people you need 13,5

for 12 people you need :

24:13.5=12:x

x=13.5/2

x=6.75

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
