Answer:
Cost = 2x + 180
Step-by-step explanation:
Let the number of pages of a book be x
Cost of the first ten pages = $20 × 10
= $200
The number of remaining pages is; x - 10
Cost of the remaining pages = $2 × (x-10)
= $(2x-20)
Total cost of the book= 200 + 2x - 20
= 2x + 180

Answer:
Step-by-step explanation:
value of 4, and you want to square it or exponent 2
so 4^2 = 4x4
=16
What is ^-2
It does the same operation however because to is negative it really means putting 4 in the denominator so 2 becomes positive. Inverse of the exponent 2
1/4^2 is the same as 4^-2
which will both give 1/16
I believe the answer is 4/15.
