Determine the value of y if x is 5.
y = 38/ x +14

y=21.6

Step-by-step explanation:

This question is based on substitute... substitution is

When a certain number is given so as to replace a certain number...

Back to the question,y=38/x+14

When x=5

Then substitute the value into the given equation,

y=38/5+14

Let the LCM be 5

y=38+70/5

Add up

108/5

y=21.6

Therefore the final answer is 21.6

there are infinitely many solutions.

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).
