Answer:
42
Step-by-step explanation:
because 2+2+2=6×7=42
X = -4y+3
-x-4y = -3
________________
x+4y = 3
-x-4y = -3
0 = 0

Answer:
$3.51
Step-by-step explanation:
We change 5.4% into a decimal which is .054, we then multiply 65 by .054
$65 x .054 = $3.51
We know that
[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x
Area=x*y-------> x*(122-x)----> 122x-x²
find the derivative function and equals to zero
122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m
<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
