It takes 3 days to complete one hour of reading. So 3 x 20 = 60 days total.
15 more. There are 3 guppies and 18 goldfish. Because 3+18=21 and 3x6=18
The answer is -16 - 10i.
Using the distributive property on the first part, we have:
-2i*7--2i*4i + (3+i)(-2+2i)
-14i+8i² +(3+i)(-2+2i)
Using FOIL on the last part,
-14i+8i²+(3*-2+3*2i+i*-2+i*2i)
-14i+8i²-6+6i-2i+2i²
-10i+8i²-6+2i²
Since we know that i = -1,
-10i+8(-1)-6+2(-1)
-10i-8-6-2
-16-10i
Step-by-step explanation:
x > -1
x = {0,1,2,...}
