Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get

on its own.
<em>Original Equation : </em>

<
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>

<

(

)
And we simplify the equation to get our answer.
<em>Old Equation :</em>

<

(

)
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation

< -3 simplified is</em>
y < -6.
Hope this helps!

Step-by-step explanation:
Answer:
924 cm²
Step-by-step explanation:
The surface area is equal to the area of the two triangles + area of the three rectangles.
Area of two triangles:
12 × (9+5) × 1/2
= 84
84(2) = 168
Area of the three rectangles:
15 × 20 + 13 × 20 + 14 × 20
= 840
840 + 84
The surface area of the triangular prism is 924 cm².
