Answer:
to find the area of a polygon
formula: area = 1/2 x perimeter x apothem
Step-by-step explanation:
Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

6/42 in simplest form :
Divide both the nominator and the denominator by the HCF (highest common factor) : 6
6/42 = 6:6/42:6 = 1/7
Answer:
1) B. n ≥ 3
2)A. 5x – 9
Step-by-step explanation:
1)
If the least value of n is 3 then all the values of n must be greater or equal to 3
Thus the correct option is B :n ≥ 3
2)
Given:
Milo's age is 9 years less than 5 times Pearl's age
Pearl's age is x years
5 times Pearl's age= 5x
then milo's age= 5x-9
so the correct option is A. 5x – 9 !
Answer:
x+3y = 6
or, x = 6-3y.................(1)
3x+5y =6..........(2)
Substituting x = 6-3y in equation (2),
3 (6 - 3 y)+5 y =6
or, 18 - 9y +5y=6
or, y = 3
x = 6 - 3y = 6- 3.-3 = -3
