To get the answer we have to multiply 25 times 21 7/8. To do that we have to transform 21 7/8 into improper fraction and thn multiply 25 times numerator.


- its the answer
Using continuity concepts, it is found that the correct options are:
- The function is continuous at x = -4.
- The function has an infinite discontinuity at x = -1.
-----------------------------
A function f(x) is continuous at x = a if:

-----------------------------
- At x = -4, there are no changes in the definition of the function, thus, it is continuous.
- At x = -1, we have that:


- A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.

I think is the last option
If segments AB and CD are congruent, then they have equal lengths:
5x-2=2x+7.
Solve this equation.
1. Separate terms with x and without x in different sides:
5x-2x=7+2,
3x=9.
2. Divide by 3:
x=3.
Then CD=2x+7=2·3+7=6+7=13.
Answer: correct choice is B.
