Conner and Alexandra are 260 feet apart when they start walking toward one another. Alexandra walks twice as fast as Conner so whenever Conner travels x feet, Alexandra travels 2 x feet. Let x represent the number of feet Conner has traveled since he started walking toward Alexandra. Write an expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another. 3x Correct Write an expression in terms of x to represent the distance (in feet) between Conner and Alexandra.

i) 3x

ii) d = 260 - 3x

Step-by-step explanation:

Given:

Conner traveled x feet

Alexandra traveled 2x feet

Total distance = 260 ft

i) The expression in terms of x to represent the total number of feet Conner and Alexandra have walked toward one another will be:

This will be the total number of feet they have walked towards one another

= x + 2x

= 3x

ii) An expression in terms of x to represent the distance (in feet) between Conner and Alexandra.

This will be to find the distance between Conner and Alexandra.

Thus, distance between them will be:

d = 260 - (x + 2x)

d = 260 - 3x

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
