Answer:
2 and 3
Step-by-step explanation:
2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio
3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.
The ratio of the perimeters is the same as the scale factor.
scale 1:4
The area of the circle is determined through the equation,
A = πr²
Plug in the value of area
36 in² = πr² ; r = 3.385 in
The formula for the circumference of the circle is,
C = 2πr
Substitute the value of radius,
C = 2π(3.385 in) = 6.77π in
Thus, the circumference of the circle is 6.77π inches.
Answer:
x=-1/2, 7/2
Step-by-step explanation:
move all terms to the left side and set them equal to zero. then set eac factor to zero
Answer:
87 / 100 I do believe will be your answer.
Step-by-step explanation:
1 is the greatest common divisor of 87 and 100, and therefore the result can't be further reduced. I hope this helps!
First, we are going to write it like this:

Then, we are going to do something like factoring, but it's not factoring. An example would be:

If we apply it, we would be left with:

We cancel the common factors, and we are left with:

That's our final answer.
Let me know if you need any more help!
Thanks!
