Area=legnth times width
width=2/3 legnth
w=2/3l
a=lw
subsitute
a=l(2/3l)
a=864
864=2/3l^2
multiply both sides by 3/2 to clear fraction
2592/2=l^2
1296=l^2
square root both sides
36=legnth
width=2/3 legnth
width=2/3 times 36
width=72/3=24
legnth =36 feet
width=24 feet
Given :
A sixth-grade student bought three cans of tennis balls for $4 each.
The sales tax for each can was $0.95.
To Find :
The total amount the student spent.
Solution :
Price of each can including taxes :
p = $( 4 + 0.95 )
p = $4.95
So, price of 3 such cans including tax is :
P = p×3
P = $( 4.95×3 )
P = $14.85
Therefore, total amount spend by the student is $14.85 .
The two equations given in the question are
4x _ 3y = 3
And
5x _ 4y = 3
Multiplying the first equation by 4 and the second equation by 3, we get
16x - 12y = 12
15x - 12y = 9
Subtracting the second equation from the first equation, we get
x = 3

Answer:
6x^2-10x-4
Step-by-step explanation:
=(3x+1)(2x-4)
=6x^2-12x+2x-4
=6x^2-10x-4
Sin^-1(5/13) = 22.6
sin(22.6/2) = 0.196
