(3-7n^2+3n^3)-(6n^3-1-5n^2). Simplify.

Answers

Answer 1

Answer:

Simplify

3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)

Simplify brackets

3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Collect like terms

(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)

Simplify

4 - 2n^2 - 3n^3

Answer 2

Answer:

Answer:

-3n^3 - 2n^2 + 4.

Step-by-step explanation:

(3-7n^2+3n^3)-(6n^3-1-5n^2)

First distribute the negative over the second parentheses:

= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Now simplify like terms:

= -3n^3 - 2n^2 + 4 (answer).

Make g the subject of the formula 3e + 4g = 7 + 9e

Answers

Answer:

g = 7 + 9e - 3e /4

Step-by-step explanation:

3e + 4g = 7 + 9e

Subtract 3e from both sides to eliminate 3e on the left side

3e - 3e + 4g = 7 + 9e - 3e

4g = 7 + 9e - 3e

Divide both sides by 4 to isolate g

4g/4 = 7 + 9e - 3e /4

g = 7 + 9e - 3e /4

Answer:

g=(7+9e-3e)/4

Step-by-step explanation:

3e+4g=7+9e

4g=7+9e-3e

g=(7+9e-3e)/4
