Answer:
22m²
Step-by-step explanation:
The area of the bases is 3m²
The area of the left and right lateral faces is 2m²
The area of the front and back lateral faces is 6m²
The lateral area of the prism = (3m² x 2) + (2m² x 2) + (6m² x 2)
= 6m² + 4m² + 12m²
= 22m²
Set up a proportion.
25/5 = x/8
Cross multiply
25*8 = 200
200/5 = x
x= 40

Answer:
392
Step-by-step explanation:
Divide by ten (98)
Multiply by 4 (392)
If the dealership sells 980 cars, then 392 of them will be black.
You minus 1.6w from both sides so
3.6w-1.6w = 24
2w = 24
w = 12
