Answer:

$(-7 + 3i)^{2} + (-2 + 8i) = 38 - 36i$

Step-by-step explanation:

(-7 + 3i)(-7 + 3i) + (-2 + 8i)

$49 - 21i -21i + 9i^{2} = 49 - 42i -9 = 40 - 42i$

40 - 42i + (-2 + 8i)

38 - 36i

Mrs Smith is completing a mathematics problem. She knows when 6 is added to four times a number, the result is 50. What would be

Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

$\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{ } \end{gathered}$

if we solve the equation we have:

$\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}$

Trevor solved the system of equations below. What mistake did he make in his work?

wariber [46]

2x + y = 5

x − 2y = 10

y = 5 − 2x

x − 2(5 − 2x) = 10

x − 10 + 4x = 10

5x − 10 = 10

add 10 to each side

5x-10+10 = 10 + 10

5x=20

5x = 0 this is the error

He needs to add 10 to each side
