Answer:

Step-by-step explanation:

Use the distributive property to get rid of the brackets.

9i + 2*7 + 2*3i Use the multiplication property to simplify the imaginary terms

9i + 2*3i + 2*7 Do the same to the real term

9i + 6i + 14 Use the addition of like terms property

15i + 14 And that's your answer.

You may not like my terminology, but you have to remember that every text teaches this differently.

Answer:

x = 10, AB = 57

Step-by-step explanation:

In a trapezoid, the length of the median is one-half the sum of the lengths of the bases. From this, we have:

$\frac{1}{2} (5x + 7 + 8x - 11) = 63$

$13x - 4 = 126$

$13x = 130$

$x = 10$

$5(10) + 7 = 50 + 7 = 57$
