2b + 6
2(b+3)
if you distribute 2(b+3), you get 2b+6
Answer:
The valid value of x is x=-2
Step-by-step explanation:
we know that
The sum of the interior angles of any quadrilateral must be equal to 360 degrees
so
solve for x
Combine like terms
Divide by 10 both sides
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
Remember that
The measure of the interior angle cannot be a negative number
For x=9
we have that the measure of one interior angle of quadrilateral is
substitute the value of x
therefore
The value of x=9 cannot be a solution
For x=-2
The measure of the interior angles are
therefore
The valid value of x is x=-2
Answer:
- 18x - 9 = 72
- 3(6x - 3) = 72
- x = 45
Step-by-step explanation:
Apply the distributed property:
- Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
- Re-write the equation: 18x - 9 = 72
- 18x - 9 = 72 is an option listed, so that's one of the answers.
See the other options:
- Another option that looks like it could be the answer is 3(6x - 3) = 72
- Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
- This is the same as what we got above, so it is also an answer.
Solve:
- Add 9 to each side, so it now looks like this: 18x = 81
- Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
- x = 45 is an option listed, so that's one of the answers.
I hope this helps!
The polar equation is r = 2 + cos(theta).
Given,
A choir is performing in front of an audience. a microphone is placed in front of the choir to capture sound.
The polar equation represents the microphone the choir is using i.e
On edge i.e r = 2 + cos(theta)
Hence, The polar equation is r = 2 + cos(theta).
