Step-by-step explanation:
Inequalities of the type | x | > a always have solutions of the form
x < - a or x > a, thus
2x + 1 < - 5 OR 2x + 1 > 5 ( subtract 1 from both sides of both inequalities
2x < - 6 OR 2x > 4 ( divide both sides of both inequalities by 2 )
x < - 3 OR x > 2
Answer:
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that
chosen x-value is said to belong to the domain of f. If there is a requirement that a y-value produced by a function
must be a real number, the following conditions are commonly checked:
1. Denominators cannot equal 0.
2. Radicands (expressions under a radical symbol) of even roots (square roots, etc)
cannot have a negative value.
3. Logarithms can only be taken of positive values.
4. In word problems physical or other real-life restrictions might be imposed, e.g. time is
nonnegative, number of items is a nonnegative integer, etc.

Answer:
A 6 cm²
Step-by-step explanation:
The formula for the Surface Area of a Rectangle Prism and Square Prism [Cube] is below:
S.A = 2hw + 2bw + 2hb
Since 1 is the length of all edges, and also because all edges are congruent on a cube, you plug in 1 for the <em>height</em>, <em>width</em><em>,</em><em> </em>and<em> </em><em>base</em>:
6 = 2[1][1] + 2[1][1] + 2[1][1]
2 2 2
Or, you can just simply plug in 1 into the formula the exercise gave you and be done with it.
