Answer:
z = 0 ; 1
Step-by-step explanation:
3 + 8 = 11 < 12
so z must be either 1 or 0
Answer:
(3n + 4) (n-2)
Step-by-step explanation:
Are you asking to factor this 3n^2 - 2n -8 ?
If so the best way to do this problem is with the X method.
top: 3*(-8)
left: factor of 3*-8 right: factor of 3*-8
bottom: -2
try the factors 4 and -6 because 4*-6 = 3 *-8 = -24
Because notice that 4 + -6 = -2
so:
3n^2 -2n - 8 can be rewritten as 3n^2 -6n + 4n - 8
We should first use Distributive property to factor: 3n^2 -6n + 4n - 8
3n^2 -6n + 4n - 8 = 3n (n - 2) + 4(n - 2)
Now we factor by grouping here : (3n + 4) (n-2)
I factored out the group (n-2)
Therefore: (3n + 4) (n-2) = 3n^2 -2n - 8
Answer:66 meters
Step-by-step explanation:
just change the negative to a positive and add them together. It would be 66.
Answer:
3x - 8
Step-by-step explanation:
the factors of the following equation
are:

If you look the equation you can notice that you don´t have a term like -48x or 48x, so the factors must have a positive and negative sign.
Remember first you need to multiply each segment and finally add.
= 
You must add all sides together to get the perimeter.
The perimeter is 24
