Answer:
(i) 2*-4 = (2+2)(-4+1)-4
= (4)(-3)-4
= -16
(ii) 7*10 = (7+2)(10+1)-4
= (9)(11)-4
= 95
(iii) -5*-8 = (-5+2)(-8+1)-4
= (-3)(-7)-4
= 17
(iv) 3*24 = (3+2)(24+1)-4
= (5)(25)-4
= 121
(v) -9*0 = (-9+2)(0+1)-4
= (-7)(1)-4
= -11

Answer:
i)-16
ii) 95
Step-by-step explanation:
i) 2* -4
Simplify the following:
= (2 + 2) (1 - 4) - 4
= (2 + 2) -3 - 4
= 4 (-3) - 4
= -12 - 4
= -(12 + 4)
= -16
Answer:
-16
ii)7 * 10
Simplify the following:
=(7 + 2) (10 + 1) - 4
=(7 + 2) 11 - 4
=9×11 - 4
=99 - 4
=95
