Aradio station is giving away tickets to a play. they plan to
give away tickets for seats that cost $10 and $20. they want to
give away at least 20 tickets. the total cost of all the tickets
they give away can be no more than $280.

Step-by-step explanation:

Let x be the number of $10 tickets the radio station gives away and y is the number of $20 tickets which the radio station gives away.

Number of tickets:

At least 20, so

Cost:

x tickets for $10 each cost $10x

y tickets for $20 each cost $20y

Total cost:

$(10x+20y)

The total cost of all the tickets they give away can be no more than $280, so

We get the system of two inequalities:

i believe it's a.

i'm not sure on this one, most likely correct.

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).
