Step-by-step explanation:
rule of thumb: whenever you have two negatives, they equal a positive! when you have one negative and one positive, it is a negative!
- let's start by going from left to right :))
- -24 -(-6) + (-31)
- -(-6) is actually + 6!
- -24 + 6 + (-31)
- +(-31) would be -31 because one - and one + is a -
- -24 + 6 - 31
- -18 - 31
- -49

1.
a.) 2q + 5r
2(7) + 5(-2)
14 - 10 = 4
b.) 3(p + 6) + q + r Plug in the numbers
3(5 + 6) + 7 - 2 Solve inside the parentheses first
3(11) + 7 - 2
33 + 5 = 38
2.
a.) m(3m + 4n)
2(3(2) + 4(3))
2(6 + 12)
2(18) = 36
b.) n²(m + p²)
(3)²(2 + (-5)²)
9(2 + 25)
9(27) = 243
c.) 3m(8 + n) + n²
3(2) (8 + 3) + 3²
6(11) + 9
66 + 9 = 75
