The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17: step 1: 5x − 2x − 3 = −2 + 17 step 2: 5x − 2x − 3 = 15 step 3: 3x − 3 = 15 which of these is most likely the next step? 3x = 5 3x = 12 3x = 18 3x = 45

The manufacturer of a new product developed the following expression to predict the monthly profit, in thousands of dollars, from sales of the productwhen it is sold at a unit price of x dollars.-0.5x^2 + 22x - 224what is represented by the zero(s) of the expression? a. the profit when the unit price is equal to 0b. the unit price(s) when the profit is equal to 0c. the profit when the unit price is greatestd. the unit price(s) when profit is greatest

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
