Directions: Calculate the percent increase or decrease between the starting and ending quantities below. Round your answer to one decimal place. Start: 3 End: 10, 2. Start: 9 End: 20, 3. Start: 100 End: 85, 4. Start: 45 End: 20, 5. Start: 30 End: 60. PLEASE HELP!!

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

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).

answer: 100
