Answer:

Step-by-step explanation:
We want to simplify:

We rewrite as:

We split the radical sign to obtain:

Simplify the square root for the perfect squares to get:

Therefore the simplified form is: 
Answer:
P = t - f
Step-by-step explanation:
First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.
let p = pages left to fill
let T = total pages needed
let F = pages already filled
Answer:2. because slope can't be negative and we just did this question.
Step-by-step explanation:
The equation of the line is (slope-intercept) y=

x+(-7) or (standard form)

x+y=-7
I got 42.5 cuz 4x+10=180 then take away 10 from both sides so 4x=170 and you divide each side by 4
