Write a proportion to find how many points a student needs to score on the test to get the given score. Test worth 50 points; test score of 84%

42

Step-by-step explanation:

Test worth = 50

To obtain a grade percent = 84%

Score to obtain = x

Using the expression :

84% of test worth = x

84/100 * 50 = x

0.84 * 50 = x

42 = x

Score to obtain = 42

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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).
