Answer:
3x^2 + 7xy + 5
Step-by-step explanation:
Lateral surface area just means the surface area, but excluding the top and base, so for a pyramid the lateral surface area would just be the surface area of all four triangles.
To find the surface area of the four triangles, you first do base × height = 32 × 24 = 768, and then divide that by 2 which is 384. Now you can just multiply this by 4 and get your answer as 1,536 square centimeters.
I hope this helps!

Answer:
<h3>X=18</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
<u><em>DISTRIBUTIVE PROPERTY:</em></u>
A(B+C)=AB+AC
A(B-C)=AB-AC
2(3x – 4) + 10 = 5(x + 4)
2(3x-4)+10 (First, expand by using distributive property.)
2*3x=6x
2*4=8
6x-8
6x-8+10
-8+10 (Add and subtract.)
-8+10=2
6x+2
5(x+4)
5*x=5x
5*4=20
5x+20
6x+2=5x+20
6x+2-2=5x+20-2 (Subtract 2 from both sides.)
20-2 (Solve.)
20-2=18
6x=5x+18
6x-5x=5x+18-5x (Then, subtract 5x from both sides.)
18-5x (Solve.)
18-5x=18
x=18
So, the correct answer is x=18.
Use the distributive property
