What is the surface area?
5 ft
4 ft
5 ft
8 ft
6 ft
square feet

152 square feet

Step-by-step explanation:

Side: 8x5=40

Side: 8x5=40

Bottom: 8x6=48

Front Triangle: 1/2(6)(4)=12

Back Triangle: 1/2(6)(4)=12

Surface Area: 40+40+48+12+12=152 square feet

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
