Claire used counters to make the pattern shown below. Pattern 1 : 1 counter, 1^2
2: 4 counters, 2^2
3: 9 counters, 3^2

True or false.
A) There are 25 counters in the 5th figure
B) There are 42 counters in the 6th figure
C) There are 81 counters in the 9th figure
D) There are 121 counters in the 11th figure

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

86

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2
