A1=12, a2=27, a3=42, etc. The pattern is that you’re always adding 15 after starting with 12. So the general rule is...
an=12+15(n-1)
So then...
a18=12+15(18-1)
a18=12+15(17)
a18=267
Answer:
Scalene triangle
Step-by-step explanation:
The sides of the triangle is ,
Since the sides are unequal . Hence it is a scalene triangle .
<h3>Hence the ∆ is scalene triangle .</h3>
No estoy segura pero 2.5 (half of the box that is 5cm)
F(-9)= 1/3(-9)^2 + 5
F(-9) = 1/3(81) + 5
= 27 + 5
= 32
Hope this helps!
