Area of field=xy=5000
perimeter of field=2(x+y)300
x+y=150
x=150-y
y(150-y)=5000

solve it
u get y= 50 or 100
then x=100 or 50
therefore the dimensions are 100m and 50m
Answer:
The graph is attached.
Step-by-step explanation:
+
= 
= -
+ 
Multiplying both sides by 4 gives;
y =
+ 6
You can graph this solution using a graphing calculator to get the answer as attached.
Answer:
<em>x = 3</em>
Step-by-step explanation:
Step 1:
Subtract 1 from both sides
2x + 1 = 7
2x + 1 - 1 = 7 - 1
<u>2x = 6</u>
(1 - 1 will cancel itself out on the side with the variable.)
Step 2:
Divide both sides by 2
2x = 6
2x ÷ 2 = 6 ÷ 2
<u>x = 6 ÷ 2</u>
(2 divide by 2, will cancel itself out on the side with the variable.)
Step 3:
Solve for x
6 ÷ 2 = 3
x = 6 ÷ 2 = 3
<u>x = 3</u>
