Answer:
96 mm^2
Step-by-step explanation:
because the cube has 6 sides and one side has a 16 mm surface area, so you would take that one sides surface area and multiply it by 6 because the cube has 6 sides, so 16*6=96 mm^2. :) arigato
Answer:
sqrt(14)
Explanation:
The absolute value of a complex number a+bi can be calculated as follows:
|a+bi| = sqrt(a^2 + b^2)
we have:
a = -4
b = -sqrt(2) i
Substitute with the values in the above equation to get the absolute value as follows:
|a+bi| = sqrt [(-4)^2 + (sqrt(2) i)^2] = sqrt(14)
Step-by-step explanation:

➷ Just work with what is inside the parenthesis
Also, move around the terms to help it make more sense:
(cosA cosB - cosA cosB + sinA sinB + sinA sinB)
As you can see, the 'cosA cosB' would cancel out through subtraction.
Now we have this:
(sinA sinB + sinA sinB)
This is just two sets of sinA sinB so it can be written as:
(2 * sinA sinB)
Simply place the values outside the parenthesis back there to get the answer
SinA sinB = 1/2 * (2 * sinA sinB)
