300/ 15 = 20
divide bar graph into 20 equal sections
each section represents one week
algebra
number of weeks = x
15x = 300
x = 300/15
x = 20
The mistake he did, was in calculating powers, when 12 is taken to numerator it becomes -12 and 6-12 is -6 and not 6 so power of x should be -6 i.e x^-6 and not x^6
So, the correct answer is
Step-by-step explanation:
We need to simplify:
Solving:
Multiplying power with the terms inside the bracket.
Now combining powers of same variable i.e if
Solving:
The exponent rule says: if

Answer:
∠ ABD = 42°
Step-by-step explanation:
∠ ODC = 90° ( angle between tangent and radius )
∠ ADC = 90° - 48° = 42°
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ ABD = ∠ ADC = 42°
