Justin has written 5 novels with an average length of 450 pages. If his sixth novel is 750 pages long, what is the average lengt

OLga [1]

Answer:

Option A: 500 pages

Explanation:

1. Number of pages of the first 5 novels

Average = [Number of pages] / [number of novels]

450 pages / novel = Number of pages / 5 novels

Number of pages = 5 novels × 450 pages / novel = 2,250 pages

2. Average length of all 6 novels

Average = [Number of pages] / [number of novels]

Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages

Average = 3,000 pages / 6 novels = 500 pages / novel

0=8x^2+8x-21 in (x-p)^2=q form

Makovka662 [10]

Step-by-step explanation:

8x² + 8x - 21 = 0

8(x² + x) - 21 = 0

8(x + 0.5)² - 23 = 0

8(x + 0.5)² = 23

(x + 0.5)² = 23/8.
