A rug is to fit in a room so that a border of even width is left on all four sides. if the room is 22 feetby 25 feet and the are
Damm [24]
--------------------------------------------------------
Find area of the border :
--------------------------------------------------------
Area of the room = 22 x 25 = 550 ft²
Area of the rug = 238 ft²
Area of the border = 550 - 238 = 312 ft²

--------------------------------------------------------
Define y:
--------------------------------------------------------
Let the width be y.

--------------------------------------------------------
Find area of the border in term of y :
--------------------------------------------------------
The area of the border =  22y x 2 + 25y x 2 - 4y² = 94y - 4y²
*We need to take away 4y² because the 4 corners will be overlap twice if we don't.

--------------------------------------------------------
Solve y :
--------------------------------------------------------
94y - 4y² = 312
4y² - 94y + 312 = 0
2y² - 47y + 156 = 0 
<span>(y - 4)(2y - 39) = 0
</span>y = 4 or y = 19.5
 
--------------------------------------------------------
Answer: The border can be 4 ft or 19.5 ft

love history [14]

Answer:

Step-by-step explanation:

Since J is the midpoint of HK,  then HJ=JK   and 3x+5=9x-3  solve for x

6x=8   x=8/6=4/3     so HJ=3x+5=3(4/3)+5=9 = JK   HK=2(9)=18

the full segment HK is 18,  each half of it is 9 =HJ=JK
