Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Let width = x ft then
2x + 2(2x) = 42
6x = 42
x = 7
so the width is 7 ft and length is 14 ft.
So the cost to build the pen = 14*1.25 + 14*1,25 + 7*2.50 + 7*2.50
= 70 answer
Answer:
Step-by-step explanation:
To find the perimeter, you would have to add all the expressions together, so you would get 2x+x+x+y+y+1+y+y
combine like terms and you will get 4x+4y+1
According to the information given in the exercise:
• 1 meter of lightning cable weight 85 grams.
,
• An empty spool weighs 260 grams.
,
• Ted weighs the partly used spool shown in the picture and its total weight is 1540 grams.
Then, knowing this, let be "x" the number of meters of cable left on the spool.
You can set up the following using the information given in the exercise:

Knowing that:

You can set up that:

Therefore, solving for "x", you get:


Hence, you can conclude that the answer is: Second option.
