Answer 1

Answer:

16X+5X-1

Step-by-step explanation:

figure it out as you read it

Answer 2

Answer:4¼

Step-by-step explanation:

g(x) = 5x - 1

x = 5x - 1

x - 5x = -1

-4x = -1

x = ¼

SINCE X = ¼

F(x) = 4x + 12x

F(x) = 4(¼) + 12(¼)

F(x) = 1 + 3

F(x) = 4

Therefore,

F(x) + g(x)

1/4 + 4

=17/4

= 4¼
