Help

-4x^2 - 6x

Step-by-step explanation:

You want to expand it by distributing terms.

2x x -2x + 2x x -3

Next, take out the constants.

(2 x -2)xx + 2x x -3

Next, simplify 2 x -2 to -4.

-4xx + 2x x -3

Then, use the product rule : x^a x^b = x^a + ^b.

-4x^2 + 2x x -3

Last, simplify 2x x -3 to -6x.

-4x^2 - 6x

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
