Answer:

x = 10.52 m

Step-by-step explanation:

Given that,

Length of a park = 90 m

Width of a park = 60 m

Area, A = 9000 m²

A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,

(90+2x)(60+2x) = 9000

4x^2 +120x +180x =5400 = 9000\\\\x=10.52\ m

So, the width of the strip is equal to 10.52 m.

If R is the midpoint of QS, RS= 2x - 4, ST = 4x-1, and RT = 8x - 43, find QS.
Pepsi [2]

Answer: QS=68 units

Step-by-step explanation:

<em>RT=RS+ST</em>

<em>8x-43=2x-4+4x-1</em>

<em>8x-43=6x-5</em>

<em>8x-43-6x=6x-5-6x</em>

<em>2x-43=-5</em>

<em>2x-43+43=-5+43</em>

<em>2x=38</em>

<em>Divide both parts of the equation by 2:</em>

<em>x=19</em>

<em>QS=RS+RQ</em>

<em>As, RS=RQ</em>

<em>QS=2RS</em>

<em>QS=(2)((2)(19)-4))</em>

<em>QS=(2)(38-4)</em>

<em>QS=(2)(34)</em>

<em>QS=68</em>
