Domain is the x value. So you would just plug in every value in the domain set into the f(x) function.
5 (-2) + 4 =
-6
5 (3) + 4 =
19
5 (5) + 4 =
29
Your answer is B.
Answer:
55 feet
Step-by-step explanation:
| - 30 - 25 | = | - 55 | = 55 feet
First four terms would be n = 1, 2, 3, 4
f(1) = 3 ( 1 )( 1 + 3 )
= 3 * 4
=12
f(2) = 3 ( 2 )( 2 + 3 )
= 6 * 5
= 30
f(3) = 3 ( 3 )( 3 + 3 )
= 9 * 6
= 54
f(4) = 3 ( 4 )( 4 + 3 )
= 12 * 7
= 84
add all the areas and n square units together i.e (23.85+29.4+26.25) in s.u.
You can circle ten tens because 10+10+10+10+10+10+10+10+10+10=100
