Question

Please could someone answer these:
1. 7f multiplied by 2g=?
2. 7f + 2g=?
3. 2p multiplied by 4p²=?
4. 2p + 4p² = ?

Answer 1

14fg
Not possible to simplify
8p^3
Not possible to simplify

Make sure you understand these too though. Go over it in your book.

Answer 2

1. 7f x 2g = 7 x 2 x f x g = 14 x f x g =14fg
2. 7f + 2g = 7f + 2g
3. 2p x 4 p² = 2 x 4 x p x p² = 8p³
4. 2p + 4p² = 2p(1 + 2p) or could be left as 2p + 4p²

Answer 3

1. 7f x 2g = 14fg

2. 7f + 2g = 7f + 2g

3. 2p x 4p^2 = 8 p^3

4. 2p + 4p^2 = 2p(1 + 2p)

NB in algebra

Addition is shown as ' a + b = a + b'
Subtraction is shown ' a - b = a - b'
Multiplication is shown as 'a x b = ab'
Division is shown as 'a divided by b = a/b'

These are normal mathematical conventions.

Answer 4

1. 14fg ?
2. 7f + 2g ?
3. 8p to power of 3
4. 2p +4p squared

you can only add like terms together......not really sure about the answers though

Answer 5

1. 7f x 2g = 14fg

2. 7f + 2g cannot be simplified

3. 2p x 4p^2 = 8p^3

4. 2p + 4p^2 = 2p(1 - 2p)

Answer 6

1. 7f multiplied by 2g=?
14gf

2. 7f + 2g=?
7f + 2g

3. 2p multiplied by 4p²=?
8p^3

4. 2p + 4p² = ?
2p + 4p^2

Answer 7

1. 14fg
2. still 7f + 2g
3. 8p^3
4. still 2p + 4p^2 or 2p(1+ 2p)

hope this help

Answer 8

1. 14fg
2. 7f+2g
3. 8p^3
4. 2p(1+2p)

Answer 9

14fg
7f+2g
8p^3
2p+4p²
