Super easy will give brainleist if done before 10 pm pls hurry. if u have time pls me on other questions you < 3

4. 17  

5. 28

Step-by-step explanation:

4. This shape can be broken up into a square and two identical triangles.

The area of a square is A=S*S

The side length of the square is 3

So the area of the square is:

A = 3 * 3

A =  9

The area of the triangle is A=(1/2)B*H

The height is 4 and the base is 2

So the area of the triangle is:

A =(1/2) * 2 * 4

A= 4

To get the total area we add the values.  Since there are two triangles, we will add the triangle area twice.

So the total area is

A = 9 + 4 + 4

A = 17

The area is 17.

5. We can split the shape into two triangles and calculate the area like that.  

Remember the area of a rectangle is

A = L*W

Area of the first triangle is

A = 4 * 5

A = 20

The area of the second triangle is

A = 4 * 2

A = 8

So the total area is 28

I dont feel like doing the rest of the problems, but the process is similar.

(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

the first option is the answer.
