Answer:
That is the simplest form.
Step-by-step explanation:
= (3x+1)(x+4)
Answer:
Equilateral triangle (Green)
60° rhombus (2 triangles) (Blue) that can be matched with two of the green triangles
30° Narrow rhombus (Beige) with the same side-length as the green triangle
Trapezoid (half hexagon or 3 triangles) (Red) that can be matched with three of the green triangles
Regular Hexagon (6 triangles) (Yellow) that can be matched with six of the green triangles
Square (Orange) with the same side-length as the green triangle
All the angles are multiples of 30° (1/12 of a circle): 30° (1×), 60° (2×), 90° (3×), 120° (4×), and 150° (5×).

<em>x
</em>
<em>2
</em>

</em>
<em>y
</em>
<em>2
</em>
<em>=
</em>
<em>16
</em>
<em>. We can do this by putting value of </em>
<em>y

<em> from first equation i.e. </em>
<em>y
</em>
<em>=

<em>k
</em>
<em>−

<em>3
