Answer:

option 4

Step-by-step explanation:

let the side of the square be s , then

length of rectangle = s + 14 and width = s - 4

Since the areas are equal then

s² = (s + 14)(s - 4) ← distribute using FOIL

s² = s² + 10s - 56 ( subtract s² - 56 from both sides )

56 = 10s ( divide both sides by 10 )

5.6 = s

Then

area of square = s² = 5.6² = 31.36 cm²

It takes Ty 4 hours 30 minutes to read his favorite book, reading at a constant rate of 100 pages
AysviL [449]

Answer:

540 pages

Step-by-step explanation:

100 pages = 50 mins

??? pages = 270 mins (converted 4hrs 30 mins to minutes)

Now you could cross multiply to find what the number of pages are:

100 pages x 270  mins = 50 mins x ??? pages

27000 = 50 mins x ??? pages

27000/50 = ??? pages

540 = ??? pages

So there are 540 pages in his favourite book.
