Answer:

<h2>The answer is A</h2><h2>A. S = 1/2p - L</h2>

Step-by-step explanation:

Step one:

given the perimeter function

P = 2S + 2L

we are expected in this problem to change the subject of the formula to S

Step two:

firstly, let us isolate the term that has S

2S=P-2L

divide both sides by 2

2S/2= (P-2L)/2

S=P/2-L

S = 1/2p - L

If you assume that there are exactly 365 days in a year, how many seconds are there in one year? Give your answer to the nearest

Elena L [17]

Answer:

31,536,000

Step-by-step explanation:

There are 3600 seconds in an hour and 24 hours in a day, so ...

(3600 s/h)(24 h/da) = 86400 s/da

Then in 365 days, there are ...

(365 da)(86400 s/da) = 31,536,000 s

-3x-2y=-1<br> 4x+6y=12<br><br> what’s all the steps and answer to this equation

abruzzese [7]

Answer:

x = -9/5

y = 16/5

Step-by-step explanation:

-3x-2y=-1 first you need to multiply the numerator by 3 so when adding

4x+6y=12 the y's cancel and you get a single variable

3(-3x-2y=-1) —> -9x - 6y = -3 then you add the like terms

4x+6y=12 —> 4x + 6y = 12

(-9x+4x) + (6y - 6y) = (-3 + 12)

-5x = 9 then you divide by -5

x = -9/5

then you plug this in to either equation

4(-9/5) + 6y = 12

-36/5 + 6y = 12 then you add 36/5 to both sides

6y = 96/5 then you divide by 6

y = 16/5

a rectangular lawn has an area of a^3 - 125. use the difference of cubes to find out the dimensions of the rectangle.

ANEK [815]

The area of a rectangle is the product of its dimensions

The dimensions of the rectangle are: $\mathbf{Length = a -5}$ and $\mathbf{Width = a^2 + 5a + 25}$

The area is given as:

$\mathbf{Area = a^3 - 125}$

Express 125 as 5^3

$\mathbf{Area = a^3 - 5^3}$

Apply difference of cubes

$\mathbf{Area = (a - 5)(a^2 + 5a + 5^2)}$

$\mathbf{Area = (a - 5)(a^2 + 5a + 25)}$

The area of a rectangle is:

$\mathbf{Area = Length \times Width}$

So, by comparison:

$\mathbf{Length = a -5}$

$\mathbf{Width = a^2 + 5a + 25}$
