Answer:
12250 ft²
Step-by-step explanation:
Let x represent the length of a partition. Then the total length of that and all of the fence segments parallel to it will be 5x. The length of the side of the rectangular area in the perpendicular direction will be ...
(700 -5x)/2
Then the total area of the 4 pens is ...
Area = (x)(700 -5x)/2 = (5/2)(x)(140 -x)
This function describes a parabola opening downward, with zeros at x=0 and x=140. Its vertex (maximum) will be halfway between those zeros, at x=70.
Then the maximum area is ...
Area = (5/2)(70)(140 -70) = (5/2)(4900) = 12,250 . . . . ft²
Answer:
480
Step-by-step explanation:
Step-by-step explanation:
4√2 + √2 = 5√2 we add 4 and the invisible 1 in front of √2, the common root stays same
8√3 - 4√3 = 4√3 subtract 4 from 8 the common root stays same
2√3 x √32 ➡ 2√3 x 4√3 too add the expressions we first need to make the roots common then add 4 and 2
Answer: <em>1575 miles</em>
Step-by-step explanation:
<em>Let's take what we are given</em>
<em>35 miles an hour</em>
<em>45 hours</em>
<em>Let's now multiply them together to get our result</em>
<em>35x45</em>
<em>1575 miles in 45 hours</em>
