#1. 7 + 3^2 (-5 + 1) ÷ 2.
#2. -3x^3 - 4x for x = -1.
#3. What is the fractional equivalent of 0.2323...?
#4. Which of the following shows the correct order of the given numbers?

1, 1, 1.6

Indicate your subject in the "School Subject" box, so those with expertise in the area will respond to the question.

1. What is divided by 2? The total? The amount in parenthesis?

2. for x = -1, -x^3 = -1

4. Correct order, if going from lowest to highest value.

If X = 0.2323... then 100X = 23.2323..., so 99X = 23.2323... - 0.2323... = 23. So X = 23/99. 23 is a prime number, so you can't simplify that any more.
