Answer:
a(n) = 7 + 3(n - 1)
Step-by-step explanation:
Notice that every term of the sequence 7, 10, 13, 16 is 3 more than the previous term. That tells us this is an arithmetic sequence with first term 7 and common difference (d) 3.
Adapting the given equation, we end up with
a(n) = 7 + 3(n - 1)
Answer:
131.25= 17.50+8.75x is the equation
Step-by-step explanation:
solve it to find x
131.25=17.50+8.75x
(subtract 17.50 from both sides)
113.75=8.75x
(divide both sides by 8.75)
13=x
Answer:
area = 520 units²
Step-by-step explanation:
divide the hexagon into 6 equal triangles.
each triangle has a base of 14 and a height of 12.1 so:
the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²
86.8 x 6 triangles = 520.8 units²
