Oliver is trying to solve the following equation by completing the square. x2−32x+31=0 Here are the steps Oliver used to complete the square. Original equation: Line 1: Line 2: Line 3: Line 4: Line 5: Line 6: x2−32x+31x2−32xx2−32x+32(x−16)2(x−1 6)2−−−−−−−−√x−16x0−31−31+3211–√±115 and x=17 Oliver did not get the correct solutions. Which line contains Oliver's first mistake?

Which speed is the fastest (use 1 mile ≈ 1.6 kilometers)? a. 12 miles/hour b. 18 feet/second c. 19 kilometers/hour d. cannot be determined

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
