1)Evaluatea² -2bcfor a = 7, b =-8, and c =3

2)Solve for x:

2(x - 2)< 61

- the answer should be x

Example:If you come up with x <-2, then you would just input -2 for your answer.

- round to two decimal places

3) Solve for x:

(8/4)x +12x = -1

- Round to two decimal places

4) Evaluate(y+z)²for y = -8 and z = 3

5) Solve for x:

2(x -2) = 8x + 5

- Round to two decimal places if necessary

6) 7X 7+ 2*(8 - 2)
