Answer: the rules are
+(+) Two like signs become a positive sign
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign
−(+)
Step-by-step explanation:
Example: 3+(+2) = 3 + 2 = 5, 6−(−3) = 6 + 3 = 9, 7+(−2) = 7 − 2 = 5,8−(+2) = 8 − 2 = 6 hope this helps you :)
(x² + 10)(6x - 5)
6x³ - 5x² + 60x - 50 or the second option
Are those all the options ?
From this question, you can conclude:
1. There are 3 decimal
2. Decimal1 + decimal2+ decimal3= 2
3. The first decimal is 0.34
If you insert the 3rd into 2nd equation, it will become:
0.34+ decimal2+ decimal3= 2
decimal2+ decimal3= 2-0.34
decimal2+ decimal3= 1.56
If there are no rules regarding the second and third decimal, then you can use this both
1.01 + 0.55
0.78 + 0.78
