Find the perimeter and area of the figure.
5 m
12 m
The perimeter is
meters.
The area is
square meters.

p=30

a=30

Step-by-step explanation:

use pythagorean theorem to find the third side (you can use this bc its a right triangle)

5^2 + 12^2 = c^2

25+144=c^2

169=c^2

13=c

perimeter = 5 + 12 + 13 = 30

using heron's formula where s equals half the perimeter =15

square root[s(s-a)(s-b)(s-c)]

square root[15(15-5)(15-12)(15-13)]

square root[15(10)(3)(2)]

square root[900]

30

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
