Answer:
-4 + 32i
Step-by-step explanation:
use the distributive property to multiply
remember: i^2 = 1
(4 - 6i)(-4 + 2i)
-16 + 8i + 24i - 12i^2
-16 + 32i - 12(- 1)
-16 + 32i +12
4 - (6 * i)) * ((-4) + (2 * i)) =
-4 + 32 i
(152.75 - 47) ÷ 11.75
Answer:56.25
Step-by-step explanation: 450 divided by 8
2(6x-1)+2(2x+5)=120
12x-2+4x+10=120
16x+8=120 |-8
16x=112 |/16
x=112/16
x=7
