Question

11. Add the additive inverse of (-12 + 16 - 42 + 3 of 7) to the product of -2, -3 and -4.​

Answer 1

Answer:

(-12+16-42+3 of 7) + (-2×-3×-4)

= (-12+16-42+3 × 7) + (+6-4)

= (-12+16-42+21) + 2

= (+4-42+21) + 2

= (-38+21) + 2

= -17+2

= Additive inverse of -17 is 17

= 17+2

= 19

Answer 2

Answer

Step by step explanation

(-12+16-42+3×7) + {(-2)×(-3)×(-4)}

(-12+16-42+3×7) + (-24)

(-12+16-42+3×7) -24

(-12+16-42+21) - 24

(16+21-12-42) -24

(37-12-42) -24

(25-42) -24

(-17) -24

( additive inverse of - 17 is 17) -24

17-24

-7
