Answer:
I'm sure you know what factorising is right so we'll group these numbers in groups of 2 so that the first bracket contains x squared plus 2x and the second one contains a x + z a then in the first bracket the common number there is xx will be outside the bracket so that we have x (x+2) then a(x+z)
Since we already know that the speed of sound is 344m per second, there are 60 seconds in one minute, and there are 60 minutes in one hour, we just multiply 344 by 60, giving us 20,640. Then we multiply 20,640 by 60 to get an answer of 1,238,400 meters per hour.
Answer:
19 Black Buttons
Step-by-step explanation:
1/4 of 40= 10
1/5 of 40= 8
10+8=18
18+4=21
So there are 21 white grey and orange.
The rest are black so 40-21=19
So 19 black buttons
Hope this helps
