7.(03.01) Consider the two groups listed below. Which statement describes the sets? (2 points)
• the length of a swimming pool
• the liquid volume of the pool
The relation (length, volume) is a function, but the relation (volume, length) is not.
The relation (volume, length) is a function, but the relation (length, volume) is not.
O Both the relation (lengtlus volume) and the relation (volume, length) are functions.
O Neither the relation (length, volume) nor the relation (volume, length) is a function.

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).

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
