Hello!
<h2>Answer:</h2><h2 />______________________________________________________
<h2>Explanation:</h2>To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A = bh
A = (12 · 5)
A = (60)
A = 30 mm²
Inner:
A = bh
A = (4 · 3)
A = (12)
A = 6
30 - 6 = 24

Answer:
8 + i
Step-by-step explanation:
What you need to simplify this is the following "definitions" of i to different powers.
Now we can sub these in for the various powers of i in our expression:
Simplifying a bit:
Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:
6 - 6i + 2 + 7i
And the final answer, in a + bi form, is
8 + i
