Angle A has a measure of 3x° and angle B has a measure of x+22°. If angles A and B are complementary, what is the value of x? *

x = 17

Step-by-step explanation: combine all of those numbers.

3x+x+22.

Combine like terms, so

4x + 22 = 90 (90 is the sum of 2 complementary angles)

Subtract 22 from both sides to get

4x = 68

Now divide by 4 to get x which is

x = 17

hi how are you doing today? if you ever need just tell me

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).
