Carlita has a swimming pool in her backyard that is rectangular with a length of 26 feet and a width of 14 feet. She wants to in
meriva

Lets solve the question,

Given dimensions are:

Length = 26 feet

Width = 14 feet

concrete walkway with width = c

After installing the concrete walkway dimensions of the walkway will be,

Length = 26 + 2c

Width = 14 + 2c

She wants to build a wooden deck around the pool with a concrete walkway of width = w

Thus the dimensions of the wooden deck around the pool will be,

Length = 26 + 2c + 2w

Width = 14 + 2c + 2w

Now the perimeter of the wooden deck will be,

Perimeter = 2(length + width)

 = 2[(26 +2c + 2w) + 2(14 + 2c + 2w)]                = 2(40 + 4c + 4w)                = (80 + 8c + 8w)

Therefore, perimeter of the wooden deck would be: 80 + 8c + 8w

Perimeter = (80 + 8c + 8w)

Andre has a summer job selling magazine subscriptions. He earns $25 each week plus $3 for every subscription he sells. Andre hop
Strike441 [17]

Answer: 25 + 3n

Step-by-step explanation:

Hi, the answer is lacking the last part:

<em>Write an expression for the amount of money he makes this week. </em>

So, to answer this we have to write an expression:

The fixed amount that he earns per week (25) plus the product of the amount he earns per subscription (3) and the number of subscriptions sold (n) , must be equal to his weekly earnings.

Mathematically speaking:

25 + 3n

Feel free to ask for more if needed or if you did not understand something.

Which numbers should be multiplied to obtain 175^2 − 124^22?
agasfer [191]
This question seems to me to be an exercise in applying the rule for a difference of squares in order to rewrite the difference of two relatively large numbers as the "simpler" product of other integers.


175^2-124^2=(175-124)(175+124)=51\cdot299=15,249

What is an equation of the line that passes through the point(2,−2) and is parallel to the line 5x-2y=4
mixer [17]

Answer:

y = 5/2x - 7

Step-by-step explanation:

5x - 2y = 4

5x - 4 = 2y

y = 5/2x - 2

Slope = 5/2

Point (2,-2)

y-intercept: -2 - (5/2)(2) = -2 - 5

= -7
