Alright, start with simplifying both sides
Than add
to both sides.
which is
After this, multiply each side by
So, your final answer is K=-7
Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585 .
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is . However, 3.14 will be used instead of for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is . However, 3.14 will be used instead of for this formula.
For the area, plug the radius into the formula, and the formula will look like . Then, solve the equation, and the answer will be 63.585 .
It is 100 because 10 times 10 = 100.
Area= Length times Width
First of all you need to push the restrictions for x so x not can being never equal 4 and -7 because than these denominators will be equal zero and these fractions undefined
1/(x-4) = 2/(x+7) cross multiple and will get
x+7 = 2(x-4)
x+7=2x-8
x = 15
hope this helped
