Tim has 56 more postcards than Paul.
Step-by-step explanation:
Total postcards boys have = 280
Let,
x = Paul's postcards
y = Shawn's postcards
z = Tim's postcards
According to given statement;
x + y + z = 280 Eqn 1
Eqn 2
Eqn 3
Putting value of y from Eqn 3 in Eqn 2
Eqn 4
Putting value of x and y from Eqn 4 and Eqn 3 in Eqn 1
Multiplying both sides by 
Putting z=120 in Eqn 3
Putting y=96 in Eqn 2
Difference of Tim and Paul = 120-64 = 56
Tim has 56 more postcards than Paul.

Y = 1/3x + 3....slope is 1/3. A parallel line will have the same slope.
y = mx + b
slope(m) = 1/3
(2,0)...x = 2 and y = 0
now we sub and find b, the y int
0 = 1/3(2) + b
0 = 2/3 + b
-2/3 = b
so ur parallel equation is : y = 1/3x - 2/3

Answer:
x = 0, x = -4, and x = 6
Step-by-step explanation:
To find the zeros of this polynomial, we can begin by factoring out a common factor of each term. 'x' is a common factor. We can distribute this variable out, giving us:
f(x) = x(x²- 2x- 24)
Now, factor the polynomial inside of the parenthesis into its simplest form. Factors of -24 that add up to -2 are -4 and 6.
f(x) = x( x + 4) (x - 6)
From this, we can derive the zeros x = 0, x = -4 and x = 6.
