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>

<h3>How do you draw a 30 degree angle with a protractor?</h3>
Step 1: Draw a line segment OQ.
Step 2: Place the center tip of the protractor at point O such that the protractor perfectly aligns with line AQ.
Step 3: Start from 'Q' on the protractor in the anti - clockwise direction and stop at 30. Mark it as point 'P'. If point 'Q' lies to the right of 'O', then start measuring clockwise and stop at 30.
Step 4: Now, place the protector at point Q, mark the point 'P' at 90, such that ∠OQP = 90.
Step 5: Join point 'P' with 'O'. ∠QOP=30° is the required 30 degree angle.

Answer:
Step-by-step explanation:
Write the sum of the terms in descending order.
Answer:
see below
Step-by-step explanation:
Because y=7x+3 and y=7x+10 have the same slope, 7, they are parallel lines. Parallel lines never intersect, so y=7x+3 will never intersect with the graph of the function y=7x+10.
MAIN POINT: If 2 lines have the same slope, they're parallel and never intersect.
