Answer:
Step-by-step explanation:
if we have 5^22 and 5^26
5^26= 5^22 x5^4
5^26 is bigger by the number 5^4
Answer: 25
Step-by-step explanation: (x-a)² = x² - 2ax + a²
From x² - 10x + k we deduce that 10x = 2·5x and a = 5
Then k = 5²2
Answer:

Step-by-step explanation:
To solve for s, you need to follow these steps.
First multiply by t both sides of the equation.


We get 
Now we divide by r, both sides of the equation.

Finallly we obtain:
or

Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's solve your system by elimination.
x−3y=9;−x+3y=−9
x−3y=9
−x+3y=−9
Add these equations to eliminate x:
0=0
<u>Answer:</u>
Infinitely many solutions.
