F(x)=7-3x g(x)=3x-7

First let’s solve for f(1)

f(1)= 7-3(1)

f(1)= 7-3

f(1)= 4 *we will save this for later

Let’s now solve for g(1)

g(1)= 3(1)-7
g(1)= 3-7
g(1)= -4

Now we can find f(1) + g(1)

f(1) =4 and g(1)= -4

4+(-4) = 0

Answer:

20 units

Step-by-step explanation:

The polygon has 4 vertices as indicated by the 4 coordinate points given.

(3, 1) and (8, 1) is a horizontal side of length 8 - 3 = 5

Similarly

(3, 6) and (8, 6) is the opposite horizontal side of length 8 - 3 = 5

Points (3, 1) and (3, 6) is a vertical side of length 6 - 1 = 5

(8, 1) and (8, 6) is the opposite side of length 6 - 1 = 5

The polygon is therefore a square of side 5 units.

Perimeter = 4 × 5 = 20 units
