Answer:

The work shown is not correct.

The subtraction sign did not get distributed to the –10i.

The sign on –10i should have changed.

The imaginary part should be 12i.

Sample response: The work shown is not correct. When the distributive property was used, the -10i should have changed to +10i, making the sum 8+12i.

theta is fancy way of saying

make degrees into radians

docker41 [41]

Answer: $a^2-b^2=3$

Step-by-step explanation:

We need to find the value of the below expression i.e.

$a^2-b^2$ when a = 2 and b = 1.

So,

Put a = 2 and b = 1 in the above expression. So,

$a^2-b^2=(2)^2-1^2\\\\=4-1\\\\=3$

Hence, the value of the expression is equal to 3.
