Let the length be x and the width be y.
<u>The perimeter is 18 in.</u>
2 ( x + y ) = 18
x + y = 9
x = 9 - y ----------------------- (1)
<u>The area is 18 in²</u>
xy = 18
x = 18/y . ----------------------- (2)
<u>Sub (1) into (2):</u>
9 - y = 18/y
<u>Multiply by y on both sides:</u>
9y - y² = 18
y² - 9y + 18 = 0
(y - 3)(y - 6) = 0
y = 3 or y = 6
<u>When y = 6</u>
x = 9 - y = 9 - 6 = 3
<u>Find the Length and Width:</u>
Length = x = 6
Width = y = 3
Answer: The length is 6 inches and the width is 3 inches.
3 % = 3 / 100 = 0.03
let number to be found = Y
of always means multiply
so....... 331 / 0.03 x Y = 57
11033.33 x Y = 57
Y = 57 / 11033.33
Y = 5.16 x 10 power -3
HOPE IT HELPS !!
dont , i know its hard but hang on :)
you can do it when pigs fly ( pigs will never be able to fly therefore youll never be able to leave )
you got this ok? if you need someone to vent to im right here !
