-23
Step-by-step explanation:
Answer:
<em>7</em>
Step-by-step explanation:
Sum of angles on a straight line is 180°
12x - 8 + 104 = 180°
12x + 96° = 180°
12x = 180° - 96°
<u>12x</u> = <u>8</u><u>4</u>
12 12
x = <em><u>7</u></em>
Answer:
geometric
Step-by-step explanation:
The differences are not constant, so the sequence cannot be arithmetic. The common ratio is -2, so the sequence is geometric.
Answer:

Step-by-step explanation:
cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise
, take out the common factor
:

Therefore, x = 0 and x = 4
- - - - - - - - -
factorised in the form (x+b)(x-b) would be 
but it is not usual to have a zero in a factorised form.
Substitute the values.
2(3)(2)=?
2*3=6
6*2=12
Final answer: 12
