17/3 most likely it depends on what was needed
Answer:
Step-by-step explanation:
Since 2 of the 3 binomials are identical I would start the distribution there.
(1 + 4i)(1 + 4i) = 
I'm sure you have learned in class by now that i-squared is = to -1, so we can make that substitution:
1 + 8i + 16(-1) which simpifies to
1 + 8i - 16 which simplifies further to
-15 + 8i. Now we need to FOIL in the last binomial:
(-15 + 8i)(-4 + 4i) = 
Combine like terms to get

Again make the substitution of i-squared = -1:
60 - 92i + 32(-1) which simplifies to
60 - 92i - 32 which simpifies, finally, to a solution of:
28 - 92i
30. is just asking where the two equations graphed intersect each other...
x = -3 and x = 1 for intersections.
Answer:

Step-by-step explanation:
There are 1,000 milliliters in a liter. This means that in order to convert 600 liters to milliliters, you must multiply 600 by 1,000.
600 x 10^3 mL simplifies to 600 x 1,000 mL
The last expression is also 600 x 1,000 mL
The incorrect expression is the first one, since it is only multiplying by 100 mL instead of 1,000.
In this question, you are given Beth velocity(8mph) and Brandon velocity(12mph). To answer this question, you will need to find the initial distance of Beth and Brandon. The calculation would be:
Initial distance= Beth velocity * duration= 8 mph * 15 minutes * hour/60 minutes= 2miles
After that, the calculation would be:
beth_velocity * time + initial distance = brandon_velocity * time
8mph * time + 2 miles= 12 mph* time
4mph * time = 2 miles
time= 2 miles / 4 mph= 1/2 hour = 30 minutes
