Answer:
Step-by-step explanation:
let x < 30 be the width of strip of lawn.
then (80-2x)(60-2x)=800
4800-160x-120x+4x²=800
4x²-280x+4000=0
x²-70 x+1000=0
x²-20x-50x+1000=0
x(x-20)-50(x-20)=0
(x-20)(x-50)=0
x=20,50
x=50(rejected)
x=20 m
If you would like to know how many feet of fencing does Laurel need in all, you can calculate this using the following steps:
square garden: 4 * 50 feet = 200 feet
3 square rose beds: 3 * 10.5 feet * 4 = 12 * 10.5 feet = 126 feet
200 feet + 126 feet = 326 feet
Laurel will need 326 feet of fencing.
Answer:
Part 1)
Part 2)
Part 3)
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
so
Part 1) Find the length of BC
Applying the Midpoint Theorem
we have
substitute the given value
solve for BC
Part 2) Find the length of DE
Applying the Midpoint Theorem
we have
substitute the given value
Part 3) Find the length of CE
we know that
----> by addition segment postulate
The point E is the midpoint segment BC
That means
so
we have
substitute
solve for CE
Answer:
B -> (-3, 9)
C -> (-3, 3)
D -> (3, 3)
E -> (3, 9)
Step-by-step explanation:
Hiya! My answer very well may be incorrect, considering that I have not seen this content in a fairly long while, but I assumed that it would be these coordinates. When reflecting across the x-axis, the goal is to flip it across the horizontal line. I assumed to leave the x coordinates be, considering how they would still be positioned along those lines, but I changed the y-coordinates to be opposite of what they were initially. By changing the y-coordinates, you can either move a figure up or down by taking the opposites of them, so I shifted the negatives to simply being positives. I hope this helped some in the very least!
