16. 8h = p 17. 288 = 18h, 16 = h. She is making $16/h, so if she works 11 hours making that same amount, 11(16) = p, she would make $176. 18. I’m not sure. 19. 24/60 = 0.4 x 100 = 40%. 20. I’m assuming you already solved it? 21. 30 x 0.63 = 18.9 22. 81 x 0.6 = 48.6 31. 40 x 0.55 = 22. Since the item is on sale for 55% this means the price decreased by $22, so 40 - 22 = 18, so Nicole payed $18. 32. 881.95 x 1.65 = $1455.22 33. 48300 x 1.38 = 66654 34. 442 x 1.35 = $596.7 35. 221/130 = 1.7 x 100 = 170 % This is all I’ll do for now, I’ll probably come back to do more if someone hasn’t by then, but I hope this helped. Just comment back on this if you have any further questions about the questions I answered :)

Answer:
x = 4.65 or x = -0.65 (to 2 d.p)
Step-by-step explanation:
To complete the square, use the formula x² + bx + c = (x + b/2)² - (b/2)² + c
- In this case, x² - 8x - 32 = (x - 4)² - 16 - 32
- This simplifies to (x - 4)² - 48 = 0
To solve this:
- First, add 48 to both sides → (x - 4)² = 48
- Next, square root both sides → x - 4 = ± √48 (remember that the square root of a number always has a positive and negative value)
- Finally, add 4 to both sides → x = 4 ± √7
x has 2 solutions
x = 2 + √7 or x = 2 - √7
x = 4.65 or x = -0.65 (to 2 d.p)
Hope this helps!
