I need help figuring out 121+2=9(-6-7P)+4P
Alex_Xolod [135]
Hi,


Work:


Equation;

121 + 2 = 9( - 6 - 7p) + 4p

First add up numbers and distribute 9 over parenthesis.

123  =  - 54 - 63p + 4p

Second: collect like terms.

123 =  - 54 - 59p

Move variable 59p to left side and change its sign.

59p + 123 =  - 54

Then move constant 123 to right side and change its sign.

59p  =  - 54 - 123

Calculate the difference.

59p =  - 177

Divide both sides of equation by 59.

p =  - 3


Hope this helps.

☆pls help no one has helped me and I'm so confused! ​
motikmotik

Answer:

Step-by-step explanation:

a). \frac{5\pm\sqrt{-4}}{3} = \frac{5}{3}\pm \frac{\sqrt{-4}}{3}

               = \frac{5}{3}\pm\frac{2\sqrt{(-1)} }{3}

               = \frac{5}{3}\pm\frac{2i}{3} [Since, i = \sqrt{(-1)}]

b). \frac{10\pm\sqrt{-16}}{2} = \frac{10}{2}\pm \frac{\sqrt{-16}}{2}

                  = 5\pm \frac{4\sqrt{-1}}{2}

                  = 5 ± 2i [Since, i = \sqrt{(-1)}]

c). \frac{-3\pm \sqrt{-144}}{6} = -\frac{3}{6}\pm \frac{\sqrt{-144}}{6}

                    = -\frac{3}{6}\pm \frac{12\sqrt{-1}}{6}

                    = -\frac{1}{2}\pm 2\sqrt{-1}

                    = -\frac{1}{2}\pm 2i [Since, i = \sqrt{(-1)}]
