Answer:
x=6*sqrt(5)
Step-by-step explanation:
We use Pythagoras' theorem:
x^2 =6^2+(24/2)^2
x^2 =6^2+12^2
x^2 =36+144
x^2=180
x=sqrt(180)
x=sqrt(9*4*5)
x=3*2*sqrt(5)
x=6*sqrt(5)
Answer:
1/2 is your answer
Step-by-step explanation:
What you do is you have to subtract the y's together and the x's together.
6-5/3-1 = 1/2
1/2 is your answer
The answer:
the main rules of the use of logarithm are
loga[a] = 1
loga[AxB] =loga[A] +loga[B] for all value positive of A and B
loga[A/B] = loga[A] - loga[B] for all value positive of A and B
in our case, <span>log8 4a (b-4/c4)
so it is equivalent to </span>log8 4a + <span>log8(b-4/c4)
and since </span>loga[A/B] = loga[A] l - oga[B] , log8(b-4/c4) =log8(b-4) - log8(c4)
the possible expression:
log8 4a (b-4/c4) = log8 4a + log8(b-4) - log8(c4)
The answer is d hope this helped
In order to subtract 2.34 from 20, the best method is using column subtraction.
To do this, we put the main number on top, and the number we are taking away underneath it.
When we set it out, we need to make sure that all the columns line up properly, the units in one line, tens in the other etc.
If taking decimals from a whole number, I would always recommend putting '0's after the decimal point for place value.
For the layout, see below:
20.00
- 2.34
Now, as we cannot subtract 4 from 0, we must begin borrowing from the neighbours.
As 2 is the nearest number, we take one from there and move it next door
1¹0.00
Do the same again, 10 becomes 9
19.¹00
And one last time
19.9¹0
Now subtract 2.34 from 19.9¹0
19.9¹0
- 2.34
10 - 4 = 6
9 - 3 = 6
9 - 2 = 7
1 - 0 = 1
17.66

Hope it makes sense, once you get your head round it you'll be fine
