One-third of a number......1/3n
increased by 12....+ 12
(1/3)n + 12
Answer:
Volume: 45000cm^3
Surface area: 6600cm^2
Step-by-step explanation:
The volume is all the side lengths multiplied, so 60*25*30 = 45,000 cm^3.
Now let's calculate the surface area.
The bottom is the width * the length, or 60*25 cm^2.
One of the sides is the length * the height, or 60*30 cm^2. This is multiplied by 2 because there are 2 of those sides.
The other pair of sides is the width * the height, or 25*30 cm^2, again multiplied by 2.
In total, the surface area is
60*25+2*60*30+2*25*30 = 6600cm^2
Answer:
Length: 20
Width:15

Answer:
what is the nth day?
Step-by-step explanation:
Answer:
( 5x-9) (5x+9)
Step-by-step explanation:
25 x^2 - 81
Rewriting
(5x)^2 -9^2
This is the difference of squares
a^2 -b^2 = ( a-b)(a+b)
(5x)^2 -9^2 = ( 5x-9) (5x+9)
