2W + 2L = 820
<span>LW = 42,000 or L = 42,000/W </span>
<span>substitute second equation into first equation: </span>
<span>2W + 2(42,000/W) = 820 </span>
<span>2W + 84,000/W = 820 </span>
<span>2W^2/W + 84,000/W = 820W/W </span>
<span>2W^2 - 820W + 84,000 = 0 </span>
<span>quadratic formula: </span>
<span>W = [820 +/- SQR(672,400 - 4(2)(84,000))]/2(2) </span>
<span>W = [820 +/- 20]/4 </span>
<span>W = 200, 210 </span>
<span>using second equation: </span>
<span>L = 42,000/200, 42,000/210 = 210, 200 </span>
<span>The dimensions of the parking lot are 200ft by 210ft.</span>
Hey!
-------------------------------------------------
I'm going to assume that the value of t is x.
-------------------------------------------------
Steps To Solve:
3(x - 2) = 6
~Distributive Property
→ 3x - 6 = 6
~Simplify
→ 3x + (-6) = 6
~Add 6 to both sides
→ 3x + (-6) + 6 = 6 + 6
~Simplify
→ 3x = 12
~Divide 3 to both sides
→ 3x/3 = 12/3
~Simplify
→ x = 4
-------------------------------------------------
Hence, x equals 4!
