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
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

X= 60 and y = 120
As we can tell x and y add up to 180 as angles on a line are equal to 180 and we know the value of x as angles in a triangle add up to 180
Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
The circle equation in standard form:
The circle equation in general form:
<u>Solution:</u>
Given that, center of a circle is (3, -2) and radius = 4.
We have to find the standard and general form of the circle.
<em><u>Finding standard form:</u></em>
The standard form of circle is
where (h, k) is center and r is radius.
So the standard form of circle is
<em><u>Finding general form:</u></em>
Now, we just have to expand the standard form to get the general form.
Hence the standard and general form are found out
