Answer:

To simplify the following expression: 6 / (7+3i), we're going to multiply and divide the entire expression by (7+3i), as follows:

\frac{6 (7-3i)}{ (7+3i)(7-3i)} = \frac{42-18i}{58} = 0.72 - 0.31i

Now, the denominator has NO imaginary numbers.

the measure of an angle is five degrees greater than six times its supplement. what is the measure of the larger angle?
Law Incorporation [45]
Let the measure of the smaller angle be x, then the larger angle is 5 + 6x and
x + 5 + 6x = 180
7x + 5 = 180
7x = 180 - 5 = 175
x = 175/7 = 25

The larger angle is 5 + 6(25) = 5 + 150 = 155 degrees.

For the function g(x)=3x^2-3x-9 what is the value of g(4)
Annette [7]
G(4) = 3x^2 - 3x - 9

Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.

g(4) = 3(4)^2 - 3(4) - 9

g(4) = 3(16) - 12 - 9

g(4) = 48 - 3

g(4) = 45

I hope this helps you!

Answer:

39 m.

The area of a triangle is calculated by the expression given as:

Area = bh/2

where b is the base and h is the height.

We calculate as follows:

270 = b (15) / 2

b = 36

hypotenuse = sqrt ( 15^2 + 36^2 ) = 39
