Answer:
The shaded region is
.
Step-by-step explanation:
The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply
.
15m is the radius of the large circle, and also the diameter of the smaller circles.
The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.
As such:

For the top angles you would solve them by setting them equal to each other, so you would do 3x+5=17x-70. You can then add 70 to both sides, getting 3x+75=17x. You can then subtract 3x from both sides, getting 75=14x. You then divide both sides, getting 5 5/14 or around 5.36 as x. You can then add plug that into 3x+5, getting around 21.07. You can then make the equation R=180-21.07. You'd get 158.93.
(6x7)x5 = 6x(7x5), hope this helps
x³y²
For this case, the first thing you should know is the properties of the exponents.
Let's write the full fraction:
(1) / (x ^ 3 * y ^ 2)
We have that by power properties:
(1) / (x ^ 3 * y ^ 2) = x ^ -3 * y ^ -2
Therefore the equivalent numerator is:
x ^ -3 * y ^ -2
Answer:
x ^ -3 * y ^ -2
I think it’s c I’m not sure :(
