<span>Simplifying
(x + 3)(x + 2)
Reorder the terms:
(3 + x)(x + 2)
Reorder the terms:
(3 + x)(2 + x)
Multiply (3 + x) * (2 + x)
(3(2 + x) + x(2 + x))
((2 * 3 + x * 3) + x(2 + x))
((6 + 3x) + x(2 + x))
(6 + 3x + (2 * x + x * x))
(6 + 3x + (2x + x2))
Combine like terms: 3x + 2x = 5x
(6 + 5x + x2)
Factor a trinomial.
(3 + x)(2 + x)
Final result:
(3 + x)(2 + x)</span>
Answer:
The solution set represented by the following graph is:
{x | x∈ R, x < -2}
Step-by-step explanation:
Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.
This means that -2 is not included in the set.
Also in interval; form the set of points that belong to the solution set are:
(-∞,-2)
in set-builder form it is written as:
{x | x∈ R, x < -2}
Answer:
20 Blocks
Step-by-step explanation:
6 Minutes 4 Blocks
----------------- = -------------------
30 Minutes 20 Blocks
Because 6 was multiplied by 5 to get 30 minutes in total then 4 blocks need to be multiplied by 5 as well.
