Find x and the length of each side if fgh is an equilateral triangle

Since the triangle is equilateral, all sides are equal. To find x, we can say that

Now simplify, and isolate x.

Therefore x=9.

Substitute x for 9 in one side.

2×9+6=18+6=24.

All sides are equal to 24 and x=9.

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
