Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
Answer:
1.false. 2.true 3.false 4.true
We know that a 20%=£15
x=the normal price of a coat =100%
20% / £15=100% / x
x=(100%*£15) / 20%=£75
Answer: the normal price of this coat would be £75.
Area = length * width
24 = l * 2/3
l = 24*3 / 2
l = 72/2
l = 36
So, The length would be 36 feet
Hope this helps!
