Step-by-step explanation:
x2 + 7x + 12
x2 + 4x + 3x + 12
x(x + 4) + 3( x + 4)
(x + 3) and (x + 4) are the factors
4x2 + 6x + 2
4x2 + 4x + 2x + 2
4x (x + 1) + 2(x + 1)
(x + 1) and (4x + 2) are the factors
The answer is B. Since the graph increases by 4 on the y-axis as <em>x</em> increases by 1, the constant of proportionality is 4.
It is 10+4
Then 10x4
The difference is 6
So these are the numbers
We can write an equation like; 5 + 3x = 35
Steps to solve:
5 - 5 + 3x = 35 - 5
3x = 30
3x/3 = 30/3
x = 10
