Answer:
169
Step-by-step explanation:
13*13=169
We can split the two 13's up:
(10+3)(10+3)
Multiply 10 with 10, 10 with 3, 3 with 10, and 3 with 3.
Basically, just multiply every single term together.
100+30+30+9
100+69
169

X+y = 15
x-y = 25
------------
2x = 40
x = 40/2
x = 20
y = 15-x
y = 15-20
y = -5
2x² - y² =
2*20² - (-5)² =
2*400 - 25 =
800 - 25 =
775
Answer: The correct answer should be x < 6
Step-by-step explanation:
When you multiplied both sides of the inequality by 3 to get rid of the /3, you didn't multiply 4 by 3.
