5(x+6)

Step-by-step explanation:

hope this is helpful

factorise an expression, we need to take out any factors that are common to each term. The process is the opposite of expanding brackets. To make sure an expression is fully factorised, we need to identify its highest common factor (HCF), ie the biggest number/letter that each term can be divided by.

Answer:

1. No

2. No

3. Yes

4. Yes

Step-by-step explanation:

The diagram has been attached

The total angle in a triangle is 180°

<CAD=45°

<ACD=90°

Therefore <ADB=45°

1. ∠ADB = 30° no

ADC = 90 - 45 = 45

∠BDC = 90 - 65 = 25

∠ADB = 45 - 25 = 20

2.△ABD ∼ △ACD no going

by law of sines

3.CD = 33.7 centimeters => yes

4.BD = 37.2 centimeters => yes
