Count the number of 1 bits after the last decimal point. Call this number n.
There will be 2^n subnets and 2^(8-n) - 2 hosts per subnet. (You can mutilply the number of subnets by the number of hosts per subnet to find the total number of hosts.)
/25: 255.255.255.128, 2 subnets, 126 hosts per subnet
/26: 255.255.255.192, 4 subnets, 62 hosts per subnet
/27: 255.255.255.224, 8 subnets, 30 hosts per subnet
/28: 255.255.255.240, 16 subnets, 14 hosts per subnet
/29: 255.255.255.248, 32 subnets, 6 hosts per subnet
Answer:
Distribute:
=(−2)(4x)+(−2)(−4)+x
=−8x+8+x
Combine Like Terms:
=−8x+8+x
=(−8x+x)+(8)
=−7x+8

Answer:
Factored form...
Step-by-step explanation:
Foil out (x-4)(x+2)=16
First: x*x=
Outer: 2*x=2x
Inner: -4*x = -4x
Last: -4*2 = -8
Combine them all:
Simplify:
What multiplies together to make -24 but adds together to make -2?
Lets list the factors of -24 to decide:
1 x -24
2 x -12
3 x -8
4 x -6
-6+4 = -2
Therefore...
