Johnetta simplified seven over nine ÷ three over eight.; her work is shown below. identify where she made her error. original division problem: seven over nine ÷ three over eight. step 1: 7 over 9 x 3 over 8 step 2: 7x 9 over 3 x 8 step 3: 21 over 72 step 4: 7 over 24 a. step 1 b. step 4 c. step 3 d. step 2

The answer is D. Step 2

She should have worked out the problem like this:

(7/9)/(3/8) = (7/9) x (8/3) = (7x8)/(9x3) = 56/27 = or 2  2/27

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
