The ratio of their area is 9/4
<h2>
Explanation:</h2>
We use ratios to compares values. In this exercise, we are comparing the circumference of two circles, which is:

and we want to know what is the ratio of their area. Recall that the circumference of a circle is given by:

If we define:

Then, the ratio of the circumference of two circles is 3:2 is:

The area of a circle is given by:

So the ratio of their area can be found as:

So:

Answers:
<h3>1. -5</h3><h3>2. 7</h3><h3>3. 1</h3><h3>4. 5</h3>
Step-by-step explanation:
Plug in the x into the equation and solve.
<h3>Value 1: X = 5</h3>
Y = -2(5) + 5
Y = -10 + 5
Y = -5
<h3>Value 2: X = -1</h3>
Y = -2(-1) + 5
Y = 2 + 5
Y = 7
<h3>Value 3: X = 2</h3>
Y = -2(2) + 5
Y = -4 + 5
Y = 1
<h3>Value 4: X = 0</h3>
Y = -2(0) + 5
Y = 0 + 5
Y = 5
I'm always happy to help :)
A=17 cm
you would need to find the volume of the shape! (:
It should be,
4x-8=2x-10 because you substitute that for y.
Now you do,
4x-2x because you do the opposite of the positive 2x as you bring it to the other side.
That is,
2x-8=10 now you bring the 8 to the other side.
2x=10+8 I added it because I do the opposite and it is a negative 8 so I add.
2x+18 now divide
x=9 that's the answer.
So the answer is, x1=-2, x2=9
x^2-7x=18
x^2-7x-18=0
x^2+2x-9x-18=0
x*(x+2)-9(x+2)=0
(x+2)*(x-9)=o
x+2=0
x-9=0
X=-2
X=9
I hope u understand!
