Which expression is equivalent to 8 (n − 2)
A 8n – 2
B) 2n – 8
C 16n
D) 8n – 16

the answer is d

Step-by-step explanation:

distributive property

8 (n - 2) = 8n - 16

A) Volume of the Triangular Prism = Area of base * Height
10cm*20cm*Height= 1200 cc
Height= 1200/200
Height= 6cm

B) Amount of cardboard used to make the sides of candy box = Total Surface Area of prism

Total Surface Area= Lateral surface Area+ Area of two side triangles
=(3*Length*Breadth)+(2*1/2*Base*height)
= (3*10*20)+(2*0.5*10*6)
=600+60
= 660 cm^2
