If the northern side has length x and the east and west sides have length y, then the cost of the fence is
<span>C = 12x + 12y + 6y </span>
<span>and the enclosed area is A = xy. </span>
<span>12x + 18y = 6000 </span>
<span>x = 500 - 1.5y </span>
<span>A = 500y - 1.5y^2 </span>
<span>A is maximized when y = 500/3. In which case x = 250. </span>
Answer:
x + 7
Step-by-step explanation:
1+7=8
2+7+9
so on
'of' in math implies that the values are being multiplied together, so multiply 47 and 65%;
47 * 65% = 47 * .65 = 30.55
Non of the above. The answer is 40 and I’m sticking to my guns !
Similar meaning you can assume they are proportionate and if every side is doubled then you should double the last. Another way is to use Pythagorean’s theorem and disregard the little triangle completely.
Both ways have me 40 !
