X² + 8x + 3 < 0

use the quadratic formula;

x = -8 + 2√13 / 2, -8 - 2√13 / 2

-4 - √13 < x < -4 + √13  (this is what they're asking as in interval notation)

hope this helps, God bless!

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.

First, distribute 5 to all terms within the parenthesis

5(w - 1) = (5)(w) + (5)(-1) = 5w - 5

Next, simplify. Combine like terms

5w - 5 - 2 = 5w + 7

5w - 7 = 5w + 7

Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides

5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)

5w - 5w = 7 + 7

0 = 14 (Untrue).

The outside diameter of the igloo is 12 feet. The thickness of each block of ice that was used to construct the igloo is 1.5 fee
mojhsa [17]
The first thing we are going to do for this case is to model the igloo as a hemisphere.
 The volume of the hemisphere is:
 V = ((4/3) * (pi) * (r ^ 3)) / 2
 Where,
 r: sphere radio
 We have then that the internal diameter is:
 di = 12-1.5
 di = 10.5 feet
 So the radio is:
 r = di / 2
 r = 10.5 / 2
 r = 5.25 feet
 Substituting values:
 V = ((4/3) * (pi) * ((5.25) ^ 3)) / 2
 V = 303.1 feet ^ 3
 Answer:
 
the amount of space of the living area inside the igloo is:
 
V = 303.1 feet ^ 3
