Answer:

8 = x

Step-by-step explanation:

all three sides are equal, so it is an equilateral triangle

if it is an equilateral triangle, each angle is 180/3 = 60 degrees

therefore

60 = 7x+4

subtract 4 from each side

60-4 = 7x+4-4

56 = 7x

divide by 7 on each side

56/7 = 7x/7

8 = x

Simplify the following expression:
jasenka [17]

The simplified form of this expression is <u>28 + 10i </u>

<h3>This question is an expression of imaginary numbers</h3>

Imaginary numbers are numbers that are composed of a real number and an imaginary part.

< To resolve this issue, let's remove the first parenthesis:

(3i + 4) - i + 4(6 + 2i)

3i + 4 - i + 4(6 + 2i)

< In the second parentheses, let's apply the distributive property:

3i + 4 - i + 4(6 + 2i)

3i + 4 - i + 4 . 6 + 4 . 2i

3i + 4 - i + 24 + 8i

< Finally, let's just sum the like terms, along with the real terms:

3i + 4 - i + 24 + 8i

10i + 4 + 24

10i + 28

<u>28 + 10i</u>

Therefore, the correct value will be <u>28 + 10i</u>
