Answer:
Step-by-step explanation:
area = length x breadth
length = 5 inches greater than width = 5+x
width = x
area = (5+x) x
104 = (5+x) x
104 = 5x + x²
x²+5x-104 =0
looking for two numbers that when you multiply gives 104, and adding it gives +5
the numbers is 13 and 8 (-13, +5)
x²+5x-13x-104 =0
x(x+5)-13(x+5) = 0
(x+5)(x-13)=0
x+5 =0 x-13 =0
x = -5, x=13
x= -5, 13
the width is either -5 or 13 inches
the length = (5+x) = (5+(-5)) = 5-5 =0
(5+x) = (5+13) = 5+13 = 18
lenth is 0 or 18 inches
The cost of one earring is 14.50. Is the tax part of it?
First, simplify the given expression: combine 1 and 9 to get 10.
Then the problem reduces to 1/3 + 1/4 + 10.
The LCD of these two fractions is 12, and so, after conversion to LCD 12, we get
4+3
----- + 10 => 10 7/12, or 127/12
12
5.12+7.68+2.88 I’d say somewhere around 13.12cm I can’t see all the answers
2/3 = 0.6666666...... (I dont know how to put a bar above the 6)
3/11 = 0.27 (with a bar above the 27
8.4 (with a bar above the 4)
