No real solution. in order to x+1 by itself you must square root both sides. that would mean square rooting -5 which creates an imaginary number. so there are no real solutions. Also cause even if x was a negative, when you'd square it, you'll always get a positive.

spin [16.1K]

Answer:

Step-by-step explanation:

Pie eaten by David and Peter = (1/4) + (2/5)

$= \frac{1*5}{4*5}+\frac{2*4}{5*4}\\\\=\frac{5}{20}+\frac{4}{20}\\\\=\frac{9}{20}$

Remaining pie = 11/20
