Answer:we know that all 3 sides are equal
so if side =a
then perimeter =3a
therefore
3a=6n-15
a=6n-15/3
a=2n-5
If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.
5x+3 is always 3 greater than 5x also.
Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)
So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4
You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.
So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004
Those are in ascending order, so that must be the right order!
So now its

but you want it in y=mx+b so
add x to both sides so that you have y on its own
so now it's
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
Answer:
20 square units
Step-by-step explanation:
If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.
