expand brackets:

8m+24=5m+45

Change sides:

8m-5m=45-24

3m=21

<u>m=7</u>

<u />

<u>z-6</u>    =  <u>3</u>

2z         4

4z-6z=24

-2z=24

Which equation shows the quadratic formula used correctly to solve 7x2 = 9+ x for x?
____ [38]

Answer:

x = (1 + sqrt(253))/14 or x = (1 - sqrt(253))/14

Step-by-step explanation:

Solve for x:

7 x^2 = x + 9

Subtract x + 9 from both sides:

7 x^2 - x - 9 = 0

x = (1 ± sqrt((-1)^2 - 4×7 (-9)))/(2×7) = (1 ± sqrt(1 + 252))/14 = (1 ± sqrt(253))/14:

Answer: x = (1 + sqrt(253))/14 or x = (1 - sqrt(253))/14
