No, because here mom is adding in 3.5 more pages when it say only 1.5. So she'll be able to read 30 pages because 1.5 and 20 pages of her friends is 30. So your answer is that her mom is wrong.
I hope this helped! I gave an explanation and an answer. You're Welcome!
Answer:
5 terms
to the fourth degree
leading coeff of 1
3 turning points
end behavior (when x -> inf, y -> inf. When x -> - inf, y -> -inf)
x intercepts are (0,-4) (0,-2) (0,1) (0,3)
Relative min: (-3.193, -25) (2.193, 25)
Relative max: (-0.5, 27.563)
Step-by-step explanation:
The terms can be counted, seperated by the + and - in the equation given.
The highest exponent is your degree.
The number before the highest term is your leading coeff, if there is no number it is 1.
The turning points are where the graph goes from falling to increasing or vice versa.
End behaviour you have to look at what why does when x goes to -inf and inf.
X int are the points at which the graph crosses the x-axis.
The relative min and max are findable if you plug in the graph on desmos or a graphing calculator.

Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
is equal to 
, because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know 
is just equal to 25, which means the simplified version of is 
.
Then we can use this new representation to finish solving.
, so the answer would be B
