Explain how to find the area of the composite figure below. Be as specific as possible, using the formulas provided. [A=bh, A=lw, A=1/2bh, A=1/2h(b1+b2)]. PLEASE HELP!

60m

Step-by-step explanation:

4×6=24 so you have that first chunk of the left side.

since 12-4= 8 you can tell that the bottom of the "triangle" is 8m

3x8÷2=12 so now youhave one part left.

since we have already inferred that the base of the triangle was 8m we know that the length of the rectangle was 8m. 8×3=24

now you add the three values. 24+12+24=60

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.
