34
16^2 = 256
30^2 = 900
900+256 = 1156
square root of 1156 = 34
Let one length be x and the other be y
x + x + y + y = 440
2x + 2y = 440
Divide by 2 through ...
x + y = 220
y = 220 - x
Area = xy
Area = x(220 -x) = 220x -

Given that that max length of x will be -b/2a
a = -1 b = 220
x =

= 110
x = 110
y = 220 - 110 = 110
Therefore max area = 110 x 110 = 12100 square yards
Answer:
(0,0) is a solution.
Step-by-step explanation:
To see if this is true you can put (0,0) into the
and
variables like so:
. When you solve this you get
so this statement is true
Ok to start with the answer,
<span>Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4.
That means angle 1 = angle 5 as well. </span>
<span>When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s.
Angle
1 = Angle 5,
Angle 2 = Angle 6, and so forth.
Since we know
angle 1 = angle 5,
we can conclude that r and s are parallel.</span>
