Answer:
21 roses
Step-by-step explanation:
49 / 7 = 7
Each friend got 7 roses.
7 x 3 = 21
3 friends combine their roses together, making a bouquet of 21 roses.
5X^4 + 2X^2 – 8
Its quadratic form is 5(x²)² +2x² -8
<span>Let be X²=p, so the final expression is 5p²+2p-8</span>
40%less
You take 36/60
That equals 60%
This means that 36 is 60% of 60
So in 24 is 40% of 60 or 36 is 40% less than 60
Answer: B and C only
Step-by-step explanation:
The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and rises 4 degrees
Initial temperature = 0
Temperature rise = 4
Fall in temperature = - 4
(Initial temperature + rise in temperature + fall in temperature)
Summing all : (0 + 4 - 4) = 0
carbon atom has 6 negatively charged electrons and 6 positively charged protons.
Net charge of atom :
(number of proton + number of electrons)
( 6 + (-6)) = 0
