Answer: x = 0
Step-by-step explanation: x+5=−5x+5
Add 5x to both sides.
x+5+5x=5
Combine x and 5x to get 6x.
6x+5=5
Subtract 5 from both sides.
6x=5−5
Subtract 5 from 5 to get 0.
6x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 6 is not equal to 0, x must be equal to 0.
x=0
Answer:
21, 24, 29
Step-by-step explanation:
Replace n with 1, 2, and 3, and do the arithmetic.
first term = 1² +20 = 21
second term = 2² +20 = 24
third term = 3² +20 = 29
The first three terms are 21, 24, 29.
