solve: √2z+3 = - z. if there are multiple solutions, list them separated by a comma, e. g., 1, 2. if there is no solution,
enter ø.

Step-by-step explanation:

+ 3 = -z

= -z - 3

Square both sides , we have

2z =

2z = + 6z + 9

re arranging the equation , we have

+ 6z - 2z + 9 = 0

+ 4z + 9 = 0

This will give a complex roots , solving by quadratic formula

z = -2 + i , -2 - i

If you mean √2z + 3 = -z, the answer is ∅

If you mean √2 z + 3 = -z

√2 z + 3 = -z

√2 z = -z - 3

√2 z + z  = - 3

z(√2 + 1) = -3

z = -3 / (√2 + 1)

z = -3 (√2 - 1)

"if it is my birthday, then it is snowing"

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
