The area of a rectangular plot 24 feet long and 16 feet wide will be doubled by adding an equal width to each side of the plot. which equation can be used to find this added width? answers

The current area is 24 times 16 or 384 square feet
double of that 768 squaer feet

the new dimetions are 24+x and 16+x

so
786=(24+x)(16+x)

an equation could be
(20(24)(16)=(24+x)(16+x)

, and

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

Using the rise/run rule. you would get 2/6.simp. 1/3
