1TH/V §11.1 + 11.2

In these two paragraphs you learnt a lot.

Good to practice some more!

-4 - 6a + 2 - 2a =

1. 6a -2
2. -8a -2
3. -8a +2
4. 2 - 8a

7g x 3g =

1. 21g
2. 10g
3. 21 g squared
4. 10 g squared

-7t x 8t =

1. 48t squared
2. 48t
3. -56 t squared
4. 56 t squared

Open your Notebook and get a pen.

Answer example 1 in the next slide:

b = 2 -10b + 7

1. b= -5 + 10b
2. b = 5 - 10b
3. b = 9 - 10b
4. b = 19b

Solution:

Answer example 2 in the next slide: 

j = 3w - 7 + 4x

1. j = -1wx
2. j = 3w -7 + 3x
3. impossible
4. j = 3wx - 7

SOLUTION: 

Answer example 3 in the next slide:

k = m + 12p - 4m - 3

1. k = 6mp
2. k = -3m + 12p - 3
3. k = 9mp - 3
4. impossible

SOLUTION:

Answer in the next slide (= ANS)

a = 3 x 2 x 5 x k x k

1. a = 12 k
2. a = 12 k squared
3. a = 30 k
4. a = 30 k squared

Solution:

ANS:

l = 6t x 5t

1. l = 30 t squared
2. l = 11t
3. l = 11t squared
4. l = t squared

ANS:

w = 3m squared x 8

1. w = 11m squared
2. impossible
3. w = 24 m squared
4. w = 24 m squared

SOLUTION:

ANS:

m = 4u x -7 x u

1. m = -28 u
2. m = -28 u squared
3. m = -11 u squared
4. m = 28u

SOLUTION:
