Please help me with this

Mathematics
1 answer:
laiz [17]3 years ago

Answer:

u= 18 square millimeters

Step-by-step explanation:

The surface area formula is A=6a^2

You plug in the given surface area (1944) into A.

Divide both sides of the equation by 6. On the left you will get 324 and on the right you will eliminate 6 and get a^2.

The only way to get rid of an exponent is to square root it, and whatever you do to one side you have to do to the other. The square root of 324 is 18 and that is your answer.

Someone please help for brainiest and thanks.. No fake answers or you get reported
bagirrra123 [75]

Hello from MrBillDoesMath!

Answer:

12/5


Discussion:

Note that 10 is a common denominator of both denominators:

9/5 = (9*2)/(5*2) = 18/10

- ( -6/10) = + (6/10)

So the original problem is equivalent to

18/10 + 6/10 =

(18 +6)/10 =

24/10 =

(2*12)/ (2*5)   =>       cancelling the common factor "2"

12/5 =

2 and 2 fifths =

22/5            (though this looks like (22)/5!)


Thank you,

MrB
