(I'll assume that the blank spaces are PLUS signs ( + ),
as they usually are on Brainly.)

The mystery complex number is  (5 - i) .

     (3 + 2i) x (5 - i)  =  (17 + 7i)

FOIL it out and you'll see it.

Find the distance between the points (<br> -<br> 10,12) and (15,12).
Nitella [24]
The distance formula is:

d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

We are given two points in the form (x,y), so plug in the values to the distance formula:

d= \sqrt{(-10-15)^2-(12-12)^2}

Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:

d= \sqrt{(-25)^2}

The square and square root cancel each other out leaving us with 25.

The answer is 25.

Find the area of this trapezoid. Area = _______ square units. Round to the nearest whole number.
fredd [130]

Answer:

119 square units

Step-by-step explanation:

To find the area of a trapezoid, use this formula: (a+b)/2 * h

Substitute 24, 10, and 7 for a, b, and h, respectively.

((24 + 10)/2) * 7

<em>Step 1: Add 24 and 10 to get 34.</em>

(34/2) * 7

<em>Step 2: Divide 34 by 2 to get 17.</em>

17 * 7

<em>Step 3: Multiply 17 by 7 to get 119</em>

119

The area of this trapezoid is 119 square units.
