Answer:
The given expression is divisible by 3 for all natural values of x.
Step-by-step explanation:
The given expression is

For x=1,

9 is divisible by 3. So, the given statement is true for x=1.
Assumed that the given statement is true for n=k.

This expression is divisible by 3. So,
.... (1)
For x=k+1




Using equation (1), we get





This expression is also divisible by 3.
Therefore the given expression is divisible by 3 for all natural values of x.

Step-by-step explanation:
Given:
RUTS is a rectangle.
To prove:
∠USR ≅ ∠SUT
Statements Reasons
1. RUTS is a rectangle 1. Given
2. RU = ST, UT = RS 2. By the definition of a rectangle
3. ∠STU = ∠SRU = 90° 3. Definition of a rectangle
4. ΔURS ≅ ΔSTU 4. By the LL theorem of congruence
5. ∠USR ≅ ∠SUT 5. CPCTC
