Asap! will give brainlist! a. y = 7 b. y = 32 c. y cannot be determined with the information given d. y = 4

If you know that the triangles are congruent then you can use CPCTC to show that 21=3x and 60=4x+8y

We can easily divide 21 by 3 which gives us x=7 so we can multiply 4 times 7 and then subtract that from 60 which gives us 32=8y and then when you solve from there you get y=4

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).
