A pentagon has 5 sides....so.....

5 x 4 = 20 ft.

V = side³

V = (y⁵)³

V = y¹⁵

2¹⁺⁴ +  0 ! =

2⁵ +  0 !  =

2⁵ + 1 =

32 + 1  =

33

we would write 7 divided by 8 as 

$$\frac{7}{8}
$ = 0.875 $ ANSWER$$

(u could also use the calculator for this)

Thank you CPhill!

yeah ! im in middle schhol!

but as u know the education system is different in in different countries so looking at this , i get to know that the period u all call homeroom , we call it a zero period!which is actually the first period when we go to schhol as its held the first but its named as zero period becoz in that children do different things!

like before it wasnt compulsory for the teacher to disscuss quizes , talk about the topics in the newspaper that the children have recieved in the class or do any helpful activity!before we sould do anything , finish homework , read a book or some people just pretended to syudy but actually they talked sofly , u know i and my friend we too did the same but sometimes we used to pass chits!lol!

but now it has been compulsary for the teacher to disscuss something useful like quiz, about the newspaper and different things!and on Thursday we have Leadership classes in which they tell us how to become a good leader , who are good leaders and all that a person needs to know to become a leader.i really find these classes boring , becoz i feel they r of no use but i think they may come use when im in senior school!

okay now for your place!

i think u people do the same things (not the friday one)

i think u should have a look here!

Good answer, rosala.....!!!

How it works. I am new, that's why. Maybe you can help me because you are in middle school, right?

6(8)=36(-7+5x)

48 = -252 + 180x    add 252 to both sides

300 = 180x              divide both sides by 180

300/180 = x  = 30/18 = 5/3

DS what is it thats confusing you?

We can't solve for x. There is no equal sign.

Your Welcome!

12) 49=7^2

log₇ 49 = 2

15)1/10=10^-1

log (1/10) = -1

10) log(little2)9-log(little2)3

log₂ 3² - log₂ 3  =

2log₂ 3 - log₂ 3 =

log₂ 3

---------------------------------------------------------------------------------------------------------------------------

16)log₇x+log₇y-log₇z   =

log₇ [(x y) / z)]

So we would solve this like!

$$\frac{-5}{4}*\frac{1}{3}$$         ( now out here we will cut or cross  multiply the two fractions,but out here we cant cut anymore so we will simply multiply it and so this will give us our answer))

$$=\frac{-5}{12}$$   $$ANSWER$$

i hope u've understood by now but if not then pls be free to ask!

hope this helps!

Thanks, rosla !!

Sure CPhill ! i'll keep aside some for u!and rest, for anonymous!

y = log (2x)

Thanks. I will try

22)  log₈ 8  .......this just asks, what power do we put on 8 to raise it to itself?? Answer.....1

26) log₅-25.......we can't take the log of a negative number (or 0).....this is undefined.......

We have

12/20 =

6/10 =

60%

144 in = 12 ft.

So

12 - 3 = 9 ft. remaining

When you subtract by a negative number it  you change the problem to an addition problem so your answer would be 36.

You can actually switch the calculator to a "fractions calculator"

y = 5x - 3

That's it ......!!!
