When n = 3:
5 + 2(3)^2
= 5 + 2(9)
= 5 + 18
= 23
Therefore, the expression 5 + 2n^2 when n = 3 equals 23.

The area of a square can be calculated using the formula A = s^2, where s is the length of one side.
Given that the side length of the square picture is 12 inches:
A = 12^2
A = 144 square inches
Therefore, the area of the picture with side lengths of 12 inches is 144 square inches. So, the answer is 144 in.^2.
Given that the side length of the square picture is 12 inches:
A = 12^2
A = 144 square inches
Therefore, the area of the picture with side lengths of 12 inches is 144 square inches. So, the answer is 144 in.^2.
what is t he volume of a box with side lengths that are 20 inches use the formula v = s^3 where s is the length of one side
400 in.^3

8,000^3
Given that the side length of the box is 20 inches, the formula for volume of a cube is V = s^3, where s is the length of one side.
Substitute s = 20 into the formula:
V = 20^3
V = 8000
Therefore, the volume of the box with side lengths of 20 inches is 8000 cubic inches. Hence, the answer is 8000 in^3.
Substitute s = 20 into the formula:
V = 20^3
V = 8000
Therefore, the volume of the box with side lengths of 20 inches is 8000 cubic inches. Hence, the answer is 8000 in^3.
write (9m)^4 without exponents.
(9m)^4 can be expanded by multiplying 9m four times:
(9m)^4 = (9m)(9m)(9m)(9m)
Multiplying the numbers and the variables together:
= 9 * 9 * 9 * 9 * m * m * m * m
= 6561m^4
Therefore, (9m)^4 written without exponents is 6561m^4.
(9m)^4 = (9m)(9m)(9m)(9m)
Multiplying the numbers and the variables together:
= 9 * 9 * 9 * 9 * m * m * m * m
= 6561m^4
Therefore, (9m)^4 written without exponents is 6561m^4.
the characters available to write (9m)^4 without exponents is +-x/()49m9m
(9m)^4 can be written as 6561m^4 by replacing the exponent symbol "^" with "x" and the multiplication symbol "*" with the available characters "+-x/()49m9m.
Therefore, (9m)^4 written without exponents using the provided characters is:
6561m4.
Therefore, (9m)^4 written without exponents using the provided characters is:
6561m4.
thats wrong though
I apologize for the mistake in my previous response.
With the characters available: +-x/()49m9m
(9m)^4 can be written as:
9m x 9m x 9m x 9m
Using the available characters, this can be written as:
9m x 9m x 9m x 9m
which translates to:
(9m)*(9m)*(9m)*(9m)
Therefore, (9m)^4 written without exponents using the provided characters is:
(9m)*(9m)*(9m)*(9m)
With the characters available: +-x/()49m9m
(9m)^4 can be written as:
9m x 9m x 9m x 9m
Using the available characters, this can be written as:
9m x 9m x 9m x 9m
which translates to:
(9m)*(9m)*(9m)*(9m)
Therefore, (9m)^4 written without exponents using the provided characters is:
(9m)*(9m)*(9m)*(9m)
