The sketch of the garden and the pond is shown below

Area of garden = length × width
Area of garden = [3x + 5] × 3x
Area of garden = 3x[3x+5]
Area of garden = 9x² + 15x

Area of pond = [x-2] × x
Area of pond = x[x-2]
Area of pond = x² - 2x

Area to be re-sod = Area of garden - Area of pond
Area to be re-sod = 9x² + 15x - [x² - 2x]
Area to be re-sod = 9x² - x² + 15x + 2x
Area to be re-sod = 8x² + 17x

The amount of sod needed to be bought would depend on how much in each packaging they are being sold.

A trick to solve these kind of problems would be...

SOHCAHTOA

Some Old Hippy Caught Another Hippy Tripping On Acid

Aka

Sin = Opposite / Hypotenuse
Cos = Adjacent / Hypotenuse
Tan = Opposite / Adjacent

Then your answer to find Sin Z...
You're looking for an angle measurement so you're going to use an inverse operation.

You'd do...

Sin = 24/40

24/40 = .6

Then you'd use your inverse so...

Z°= Sin^-1(.6)

Z = 36.8698°

Rounding

Z = 36.870°

If you're using a scientific calculator. Make sure to put your calculator in degree mode to find the angle measurements and in radians to find missing side lengths.

-(7-2x) + 7 = -7<br><br> What is X?
Mekhanik [1.2K]

Answer: x= -\frac{7}{2} = -3 \frac{1}{2} = -3.5

Step-by-step explanation:

−(7−2x)+7=−7

To find the opposite of 7−2x, find the opposite of each term.

−7−(−2x)+7=−7

The opposite of −2x is 2x.

−7+2x+7=−7

Add −7 and 7 to get 0.

2x=−7

Divide both sides by 2.

x = \frac{-7}{2}

Fraction  −7/2 can be rewritten as −2/7 by extracting the negative sign.

x = -\frac{7}{2}

The sum of three consecutive odd numbers is one hundred fifty-nine
xeze [42]
First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.
