Answer:
x = -2, x = -1
Step-by-step explanation:
A graphing calculator solves this nicely, as shown in the attachment.
x = -2, x = -1
__
The given equation resolves to two equations.
<u>x+3 < 0</u>
-(x +3) -1 = (x +2)^2
x^2 +5x +7 = 0
Checking the discriminant, we find ...
b^2 -4ac = (5)^2 -4(1)(7) = 25 -28 = -3
There are only complex solutions to this equation.
__
<u>x+3 ≥ 0</u>
x +3 -1 = (x +2)^2
(x +2)^2 -(x +2) = 0 . . . .subtract x+2
(x +2)(x +2 -1) = 0 . . . . . factor
Solutions are values of x that make these factors zero.
x +2 = 0 ⇒ x = -2
x +1 = 0 ⇒ x = -1
<em>Domain Check</em>
x +3 = -2 +3 = 1 > 0 . . . . as required.

Step-by-step explanation:
If Mira has 10 more bottles than Noura, what Noura has, just add 10 to it, and that will be how many bottles Mira has.
For the table, if Noura has 2 bottles, 2 + 10 = 12, so Mira would have 12 bottles.
To find how many bottles Noura has, subtract 10 from whatever Mira has.
For example, from the table, Mira has 11 bottles in the 3rd column, so 11 - 10 = 1, so Noura would have 1 bottle.
For the number sentence:
n more than 10 equals m
Unless you're looking for an equation:
n + 10 = m
