Answer:

1) 20

2) 4

Explanation:

1)

I) Substitute t with 2:

2² + 5(2) + 6

II) Simplify/Evaluate:

2² + 5(2) + 6

4 + 10 + 6

14 + 6

20

2)

I) Setup the equation:

g(t) = 5t - 2 = 18

5t - 2 = 18

II) Solve it:

Reorder the terms:

-2 + 5t = 18

Add 2 to each side of the equation:

-2 + 2 + 5t = 18 + 2

Simplify:

0 + 5t = 18 + 2

5t = 18 + 2

5t = 20

Divide each side by 5:

t = 4

Hope I helped :)
