The possible dimensions are -7 and -8 units.

Solution:

Area of the rectangular skateboard park =

To find the dimensions of the park.

Let us factor the polynomial:

15x can be written as 7x + 8x.

Take x common in 1st two terms and 8 common in next two terms.

Make sure that the remaining terms in the bracket should be equal.

Now, take the common term (x + 7) outside from both terms.

If the length of the park is -7 then the width is -8.

If the length of the park is -8 then the width is -7.

The possible dimensions are -7 and -8 units.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
