Answer:

I did not understand your question so this is what I know. If it is correct pls mark me brainliest.

Step-by-step explanation:

15 + -4j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + -4j = 0 + -15

Combine like terms: 15 + -15 = 0

0 + -4j = 0 + -15

-4j = 0 + -15

Combine like terms: 0 + -15 = -15

-4j = -15

Divide each side by '-4'.

j = 3.75

Simplifying

j = 3.75

Answer:

15 + -4j = 43

Solving

15 + -4j = 43

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + -4j = 43 + -15

Combine like terms: 15 + -15 = 0

0 + -4j = 43 + -15

-4j = 43 + -15

Combine like terms: 43 + -15 = 28

-4j = 28

Divide each side by '-4'.

j = -7

Simplifying

j = -7

How to solve this equation?
Novay_Z [31]

Answer:

x = √(28), or x = 5.292

Step-by-step explanation:

First you distribute the square to the values inside of the parentheses. so it ends up looking like this

5(x^2 - 25) - 9 = 6

add 9 to both sides

so its 5(x^2 - 25) = 15

Then distribute the multiplication of 5 to the contents within the parentheses

so it would be 5x^2 - 125 = 15

add 125 to both sides

you get 5x^2 = 140

divide by 5 on both sides

you get x^2=28

then, take the square root of both sides to reverse the square

√(x^2)=√(28)

and in the end you get x=5.292

but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
