How do I solve this?

Step-by-step explanation:

Base = 25 ft

height = 8 ft

Area of triangle =

100 ft²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 25 ( parallel to the base of the rectangle ) and h = 8, then

A = × 25 × 8 = 12.5 × 8 = 100 ft²

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.
