Cos(x) = sqrt 2/2 Tan(x) = 1
your calculation is (40+7.50)x?=12.50x? i think
Pythagoras theorem: a^2 + b^2= c^2
Where c is the hypotenuse.
You can also have: c^2-a^2=b^2
3x+54
Lol, useful.
and no, im not spanish
im just taking it for my GCSE so i cn kind of understand it
Thank you for the translation.
Are you spanish?
Unfortunately, I still cannot do this question though.
For breakfast you prepare soluble coffee 600 ml of water (1000 ml = 1000 g water) at 92 ° C. If you take 200 ml in a cup, to which you add 25 g of water at 15 ° C to lower its temperature: What is the final temperature of coffee? It considers that the specific heat is the same for water and brewed coffee. The remaining 400 ml of the empty brewed coffee in a thermos and as has cooled a little while acctually now has a temperature of 89 ° C. At noon, when you take your coffee at lunch you realize that you have the same temperature. Why the temperature of the brewed coffee in the thermos remained? Who wins heat? What is the magnitude of the gain? What is the temperature of the thermal equilibrium?
you do the perenteses ( ) first than you do the square root like an exponet and continue solving the equation
You cannot solve this as it is not an equation, however you can simplify it.
x+x+48 will become 2x+48
The recurring symbol is a small dot on top of the number that will go on for ever
If it is a pattern of numbers that are constantly repeating then the dot will be on the first number of the sequence and the last number
BODMAS- There fore you will do the division first, then the multiplication
22/2=11
11*36=396
7q-11=-10q
You then - 7q from both sides
-11=-17q
Then you divide by -17 to get:
q=11/17
You need a value for x and F(x) before you can find a value for a.

x2-7x+12
(a+b)(c+d) = ac + ad + bc + bd
Simplify the following: 2 (x-3)+7 (x+2)
2 (x-3) = 2 x-6: 2 x-6+7 (x+2)
7 (x+2) = 7 x+14: 7 x+14+2 x-6
Grouping like terms, 7 x+2 x-6+14 = (2 x+7 x)+(-6+14): (2 x+7 x)+(-6+14)
2 x+7 x = 9 x: 9 x+(-6+14)
14-6 = 8: Answer: | 9x + 8
265,000,000=2.65 x 10^8
