Jack is mowing a lawn that has a shed. needs to know area of lawn to mow. dimensions of yard are 5x by 13 x-4 . she'd are 2x by
Elena-2011 [213]
The diagram of the lawn and the shed is shown below.

The area of the lawn needed to be mowed equals to the area of the yard minus the area of the shed

The area of the yard = (5x)(13x-4) = 65 x^{2} -20x
The area of the shed = (2x)(2x+4)=4 x^{2} +8x

The area of the lawn = 65 x^{2} -20x-(4 x^{2} +8x)
The area of the lawn = 65 x^{2} -20x-4 x^{2} -8x
The area of the lawn = 61 x^{2} -28x

Solve the Equation.
IgorLugansk [536]
<h2>1.</h2>

Firstly, combine like terms: 7r-8=10+r

Next, subtract r on both sides of the equation: 6r-8=10

Next, add 8 onto both sides of the equation: 6r=18

Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>

<h2>2.</h2>

Firstly, multiply both sides by e: TE=3u

Lastly, divide both sides by 3, and <em><u>your answer will be \frac{TE}{3}=u</u></em>
