PLZ ASAP! ( MATH ) FIRST ONE GETS BRAINLIST, A THANK YOU AND POINTS 1.Choose data for at least two of the students. For each student, estimate the fraction of the book read on both days. Explain your estimate.

2.Calculate the exact fraction of the book read on both days for at least two students. Write an addition equation for each student you choose.

What is the expression in factored form? -x^2 + 3x + 28 a. (x-7)(x-4) b. -(x-7)(x+4) c. (x+4)(x+7) d. -(x-4)(x+7)

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?

How do the number line graphs of the solutions sets of -23 > x and x-23 differ?
