Answer:
All those canbe expressed in the form of p/q, where q≠0 are rational
clearly A is rational
now 0.62 =62/100=31/50----its also rational
and 0.6 =6/10=3/5--- it's also rational
0.6π =(3/5)π, 3/5 is rational but π is irrational so overall it's irrational!
A,B&C are rational!

The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)
In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0.
x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x - 8) in our factorization.
You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.
Here, Area of a Triangle = 1/2 * b * h
A = 1/2 * 6 * 8
A = 1/2 * 48
A = 24
Area of two traingles = 2(24) = 48
Now, Area of a rectangle = 25 * 5 = 125
Now, Total area of the figure = 125 + 48 = 173 units2
In short, Your Answer would be Option A
Hope this helps!
Answer:
step 3: he should have divided both sides by -7
the next term is 1 because 64 divide by 16 is 4 which means the geometric sequence is decreasing by 4
