I" GIVE FIVE STAARS AND BRAINLIEST Figure 1- 6 blocks
figure 2- 11 blocks
Figure 3- 18 blocks
Which of the following functions represents f(n), the number of small squares in figure n?
a. f(n)=4n^2+2
b. f(n)=n^2+5
c. f(n)=(n+1)^2+2
d. f(n)=(n+1) (n+2)

c. f(n) = (n+1)^2 + 2

Step-by-step explanation:

It is c. because...

f(n) = (1+1)^2 + 2

        2^2 + 2

        4 + 2 = 6 (first term)

f(n) = (2+1)^2 + 2

        3^2 + 2

        9 + 2 = 11 (second term)

f(n) = (3+1)^2 + 2

        4^2 + 2

        16 + 2 = 18 (third term)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
