The equation x3 – 6x = 72 has a solution between 4 and 5 Use a trial and improvement method to find this solution. Give your answer correct to one decimal place. You must show all your working

 x3 – 6x = 72, If this means=x^3 - 6x=72,

x=4.6390, you can only solve this using advanced methods such as "interpolation" and possibly, graphing methods.

3/4(8x+12)=15

6x + 9=15

6x=15 - 9

6x=6

x=6/6

x=1

I have been busy doing this assuming that     i = sqrt(-1)

BUT

looking at it this looks like a compund interest question, so our answering guest is correct, you probably need to give us the value of i  (interest rate per compounding period.)

Thanks guest.  :)

Are you asking "How much would a party of 45 people cost?" If yes, then we have:

$45/10=$4.5 cost per person,

$4.5 X 45=$202.50 The cost for a party of 45 people.

if a=14 then what is 4a+8=10

4a+8=10=(4*14) + 8=56 + 8=64

1000(1+i)^25

What is the value of i? Did you forget something?

13s-31=2s-9

13s - 2s=-9 + 31

11s=22

s=22/11

s=2

What is the nth term for -4, -11, -18, -25 & -32?

The common difference is -7. Just add it to the next term: -32-7=-39-7=-46-7=-53......etc.

8x8x8x8x8=8⁵

8⁵=32,768.

\(1.2+(π-1.2)=n\)

Simple!

(Also, if you simplify π to 3.14159, then the answer is 2.04159.)

\(1.2+2.04159=π\)

99 + 9/9  = 199

 next to 0 is a (-) push it then put in your number

four and eight tenths

h/9

The sum of the first 10 terms of an arithmetic series is 576. The common difference is -8. Determine the value of the first term, t1.

The first term=93.6

If your question is: 1x/2x=5/4, then it is NOT right. Talk to your teacher.

P=2L+2w;L=97,W=146

P=(2*97) + (2*146)

P=194 + 292

P=486

360=x+6

x=360 - 6

x=354

40 + x = 12x

40=12x - x

40=11x

x=40/11=3 7/11

294!

Do you understand what that means? Are you just curious? At any rate here is the answer to your question=294!=4.414933 X 10^599

I thinked more in it and I reached to the answer 

the answers are C and B 

Hallo guest

300ml:1.5L

I don't know what you want, so here is my take:

1L=1,000ml, so 1.5L=1,500ml

300ml:1,500ml=1ml:5ml
