X=lebgth
y=width.
I suggest this system of equations:
x=2y
(x+4)(y+4) - xy=88
we can solve this system by substitution method.
(2y+4)(y+4)-2y(y)=88
2y²+8y+4y+16-2y²=88
12y=88-16
12y=72
y=72/12
y=6
x=2y
x=2(6)=12
Answer: the dimensions of the original rectangle are:
length=12 m
width=6 m
Answer:
irrational number
Step-by-step explanation:
Irrational numbers are not repeating or terminating.
These type of numbers are called irrational numbers.
So it is an irrational number

Answer:
480 yds.
Step-by-step explanation:
Model is 12in X 24in
Scale is 1in = 4 yds
24 in is the length, so multiply the 24 and 4 to find length of the actual field.
24 *4 = 96 yds. Manny ran it 5 times, multiply 96 and 5. 96 * 5 = 480 yds.

Answer: (x - 5, y - 6)</h3>
=====================================
Explanation:
Let's say that point P is at (0,0). Using the original rule (x+5, y+6), we would add 5 to the x coordinate and 6 to the y coordinate to land at (5,6) which is point P '
Now the teacher wants you to start with point P ' and move back to point P. The rule to do this is basically the inverse or opposite of what the original rule states.
Instead of "add 5 to x", we "subtract 5 from x" to have x-5 as part of the rule. Similarly, undoing "add 6 to y" means we have "subtract 6 from y" to have y-6.
That's how (x-5, y-6) is the complete opposite or inverse of (x+5, y+6)
The first rule shifts P five units to the right and six units up to land on P'
The second rule moves P ' five units to the left and six units down.
If you apply either rule in any order, but do so together, then the point always goes back to its original starting location.
