Answer:
1) There are two definitions Charlotte came up with to define the quantity:
• Number of new subscribers divided by number of posts
• Number of new subscribers divided by number of words
2) No. The definitions have opposite results
4x^2-25= (2x)^2-5^2=(2x-5)(2x+5)
Used: a^2-b^2=(a+b)(a-b)
Answer:
A. 5x^2 - 2x - 12 = 0
Step-by-step explanation:
The base is x feet.
The height is 2 less that 5 times the base.
The height is 5x - 2.
The area is 12.
The area is base * height / 2.
area = bh/2
area = x * (5x - 2) = 12
5x^2 - 2x = 12
5x^2 - 2x - 12 = 0
