(9m+6) + (-5m-6)
4m - 12
the bot messed up again
(9m+6) + (-5m-6)
= 9m + 6 - 5m - 6
= 4m
I apologize for the mistake. You are correct that the simplified expression for (9m+6) + (-5m-6) is 4m. Thank you for correcting me!
(9m+6) + (-5m-6)
a. 4m+12
b.14m=12
c. 14m-12
d. 4m
The simplified expression for (9m+6) + (-5m-6) is 4m. Therefore, the answer is option d) 4m.
(3r^2 + 7r +1) + (4r^2 - 8r -2)
a. 7r^2+ 15r - 1
b. 7r^2 - 15r - 3
c. 7r^2 - 15r - 3
d. -r^2 - r - 1
(3r^2 + 7r +1) + (4r^2 - 8r -2)
First, we can combine like terms to simplify the expression.
= 3r^2 + 4r^2 + 7r - 8r + 1 - 2
= 7r^2 - r - 1
Therefore, the answer is option d) -r^2 - r - 1.
(6h+1) - (9h + 4)
(6h+1) - (9h + 4)
First, we distribute the negative sign to the terms inside the parentheses.
= 6h + 1 - 9h - 4
Then, we can combine like terms to simplify the expression.
= -3h - 3
Therefore, the answer is -3h - 3.
