"Completing the square" is a step in the solution of quadratic equations. It can be accomplished without the guesswork or trial-and-error associated with methods like factoring, and it always leads to a solution. It is the method by which the quadratic formula is derived.
<em>312 ft²</em>
- Step-by-step explanation:
<em>3 rectangles
</em>
<em>2 triangles</em>
<em>4 yd = 12 ft</em>
<em>A = 4ft×12ft + 8ft×12ft + 10ft×12ft + 2×6ft×8ft/2</em>
<em>= 48ft² + 96ft² + 120ft² + 48ft²</em>
<em>= 312 ft²</em>
The correct answer is 50%.
Approximately the middle 50% of data is contained inside the box of a box plot.
Answer:
84 in^2
Step-by-step explanation:
Find the area by first finding the average of 10 and 14 (it is 12) and then multiplying this result (12) by 6: area of trapezoid = 84 in^2.
