Answer:

A, B, C, D, E

Step-by-step explanation:

AB ≅ AC and AD bisects ∠A

This is given information from the diagram and the statement.

∠BAD ≅ ∠CAD

This is from the definition of angle bisector.

AD ≅ AD

This is reflective property of congruence.

ΔABD ≅ ΔACD

From the previous three statements, side-angle-side congruence tells us the triangles are congruent.

∠B ≅ ∠C

Corresponding parts of congruent triangles are congruent.

Remark

Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.

Solution

(x - 7)^2 - 25 = 0 Add 25 to both sides

(x - 7)^2 - 25 + 25 = 25 Combine the left

(x - 7)^2 = 25 Take the square root of both sides.

sqrt(x - 7)^2 = sqrt(25)

x - 7 = +/- 5 Add 7 to both sides

x = 7 +/- 5

=========

x1 = 7 + 5

x1 = 12

x2 = 7 - 5

x2 = 2

Smallest x = 2

Largest x = 12

Answer:

Option C. The open and closed circles are reversed and the graph shifts up.

Step-by-step explanation:

From the graph of the functions (Attached below) you can check that for the interval 0 ≤x<1 the floor function takes the value 0 everywhere, also it has closed brackets at 0 and open brackets at 1.

On the other hand for the interval 0<x≤1 the ceiling function takes the value 1, also it has open brackets at 0 and closed brackets at 1.

For that reason we conclude that the open and closed circles are reversed and the graph shifts up.
