Marvin goes school shopping. he buys 3 pairs of jeans, 8 tee shirts, and 2 pairs of shoes.

answer questions 3a, 3b, 3c and 3c

3A : 3(a)+8(b)+2(c)

3B:  3(20)+8(8.50)+2(40)=208

3C: 208-15%=208*0.15=31.2

                 208-31.2=176.8

3D:  176.8+6%=176.8*1.06

                    187.41

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).

the answer is
