Answer:
Area of a regular polygon formulas
Step-by-step explanation:
area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides)
area = perimeter * ri / 2 , given ri and polygon perimeter.
area = n * (ri)² * tan(π/n) , given ri.
Answer:
x^8
Step-by-step explanation:
x^3 x x^5
=x3*x5
=(x*x*x) * (x*x*x*x*x)
=x*x*x*x*x*x*x*x
=x8
Answer:
A=5
Step-by-step explanation:frac{15s}{15}=frac{75}{15}
divide both sides by 15
so what you have to do is multiply 3 and 2 and 3 and -14 which ends up being 6x-42x=, then do 15 times -9 and you then do 15 times -5 and that becomes -135x - (-7) then you show it like this= 6x-42x=135x-(-7) the solution would be 36x=-135 divide 36 each side and you get x= 2.28

Answer:
Step-by-step explanation:
If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...
x(x +2) = 63
__
The equation can be rewritten as ...
(x +1)² = 64
x = -1 ±√64 = -1 ±8
The positive solution is x=7, so the positive set of integers is {7, 9}.
The negative solution is x=-9, so the negative set of integers is {-9, -7}.
