.04 Im pretty sure this is the answer
Answer:
A and B is correct ...............
Step-by-step explanation:
2√48= 13.86
3√147= 36.37
Perimeter: 13.86+13.86+36.37+36.37= 100.46
Answer:
The equation that models the relationships between
, the number of hours Mark reads, and ,
the number of pages of the book he reads is:

Step-by-step explanation:
Given:
Mark reads 42 pages every
hour.
The number of hours is given by = 
The number of pages is given by =
The equation can be modeled as:

where
represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value
as Mark starts reading from 0.
So, the equation is:

Answer:
5.055 m by 13.055 m
Step-by-step explanation:
Let x represent the width of the room in meters. Then the length is x+8 meters, and the room area is ...
A = LW = (x+8)(x) = 2(rug area)
x^2 +8x = 2(3)(11) = 66
Completing the square, we have ...
x^2 +8x +16 = 82
(x +4)^2 = 82
x = -4 ±√82 ≈ {-13.055, +5.055}
The magnitudes of these dimensions are the dimensions of the room:
√82 ± 4 = {5.055, 13.055} . . . meters
Therefore, the room is 5.055 × 13.055 meters.
