Answer:
x = -2 or x=-5
Step-by-step explanation:
sqrt(x+6)-4 = x
sqrt(x+6) = x+4
square both sides
x+6 = x²+8x+16
x²+7x+10 = 0
(x+2)(x+5) = 0
x = -2 or x=-5
Substitute in original equation
x=-2 +/- sqrt(-2+6)-4 = 2-4 = -2 checks
x=-5 +/- sqrt(-5+6)-4 = -1-4 = -5 checks

Step-by-step explanation:
minus and minus are cut . Hope it helps..
so if 5.5 is in meter let change it to cm because the question want us to give the answer in cm.
now we multiply 5.5 times 100 which is equal to 550.
next we subtract 550 - 220= 330.
finally, the difference between a teacher and student is 330cm .meaning the teacher's desk is 330 cm longer or taller than the student.
