Hey there!:
4r -3 + 6s - 8r - (4s - 6)
*distribute parentheses :
= - ( 4s ) - ( - 6 )
Apply minus - plus rules
- ( - a ) = a ; - ( a ) = - a
= - 4s + 6
4r -3+ 6 s - 8r -4s + 6 =
Group like terms :
=4r - 8r + 6s - 4s -3+6
Add similar elements: 4r - 8r= - 4r
-4r + 6s - 4s- 3+6
6s - 4s = 2s
-4r + 2s - 3 + 6
Add/Subtract the numbers :
-3 + 6 = 3
Therefore:
= 2s +3 - 4r
hope this helps!
Answer:
I believe the answer is 400 operations per second.
Step-by-step explanation:
The graph crosses the x axis where g(x) = 0 , so:-
x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5
so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)
Answer:
30 basketballs
Step-by-step explanation:
one layer would be 3 x 2 = 6
- to find how much you would need to cover the bottom of the locker, you would use the numbers 3 and 2, then multiply them and you get 6. You would need 6 basketballs to cover the bottom of the locker. That would be your first layer
5 layers would be 6 x 5 = 30
- So the bottom would be filled with 6 basketballs. Now since the locker is 5 feet high multiply 6 x 5 and that would get you your total of basketballs
Answer:
<u>a= -4</u>
