The cost of the bench is $150.
300÷2= 150
150+300= 450
Hope this helps! :)

If we can write a polynomial in the form
, then we can factor it as:

In this problem, we have the following expressions:

- For 1 and 4 we can't write this in the form
so this is not a difference of squares.

So we could write 2 as a difference of squares.

So we could write 2 as a difference of squares.
this question is not complete
If you're asking for points that would be on the graph of that quation then 1,9 and 2,14 work
As the general formular for a straight line is

m represents the gradient
c represents the point at which the line crosses the y axis.
Therefore you simply plug the numbers into the equation.

You can work out whether 2 lines are perpendicular by multiplying their gradients. The product of the gradient of perpendicular lines will always be -1.
If lines are perpendicular, M1× M2 = − 1
So you can rearrange the equation to get M2=-1/M1.
As they perpendicular they have to intercept at the same point on the Y axis therefore you get the equation
