What is this the answer?

c) 14

Step-by-step explanation:

f(x) = x²

f(-3) = (-3)² = -3 * - 3 = 9

g(x) = 2x - 3

g(4) = 2*4 - 3 = 8 - 3 = 5

g(4) + f(-3)  = 5 + 9

                 = 14

Option B is correct

42

Step-by-step explanation:

Area of parallelogram(A) is given by:

where;

b is the base and h is the height of the parallelogram.

As per the statement:

Seth wants to cover the top of a small table with glass parallelogram tiles. The top of the table measures 18 inches by 14 inches.

⇒b = 18 inches and h = 14 inches

then;

It is also given that:

If each tile has four sides of length 3 inches with a height of 2 inches

then;

where, A' is the area of each tiles.

We have to find how many tiles will he need.

⇒

⇒Number of tiles =42

Therefore, 42 tiles will he need.
