63+86+77 it =s 226 so thank you for asking am only 9 am in 4 grade its easy look it up on the calculator but I did not use it believe me
(f+g)(x)=f(x)+g(x)= 3x+5 + (-2x^2-5x+3) = -2x^2 -2x+8 (B)
To solve this problem, we make use of the formula of
combination.
nCr = n! / r! (n – r)!
where n is the total number of subject teachers and r is
the number of subjects r = 1
For the English class n = 3
3C1 = 3! / 1! (3 – 1)! = 3
For the Algebra class n = 4
4C1 = 4! / 1! (4 – 1)! = 4
For the Biology class n = 2
2C1 = 2! / 1! (2 – 1)! = 2
The total number of different schedules would be the
product of the three combinations:
total combinations possible = 3 * 4 * 2
total combinations possible = 24
Answer:
2600
Step-by-step explanation:
Just simply multiply 130 x 20 because for every sheet it only takes 1/20 of the ream. You should get 2600
To solve this question you will need to subtract -3.8 by 5.6 which is equal to -9.4. So the final answer is -9.4°C
. Setting that up so the meters cancel as they should looks like this: 
lets us divide as we need to and at the same time cancel out the distance, leaving us time in hours. The t value then is 11.3 hours.
