Okay so 0.4 is equal to 4/10 (hopefully you know that!) & anything over 1 is itself so i would but 64 over 1.
so now you hace 2 fractions & when dicing fractions you alwas flip the second fraction upside down & then just multiply across.
so if you have
64 4
---- / ----
1 10
you would switch the 2nd one so the 10 would be on top.
so that would give you 64*10 over 1*4
which equals 640/4
& when you simplify that you get 160
so that's your answer(:
Given x ^2 −3x+2=0
x ^2 −2x−1x+2=0
(Resolving the expression)
x(x−2)−1(x−2)=0 (Taking common factors)
(x−2)(x−1)=0 (Taking common factors)
∴x−2=0 or x−1=0 (Equating each factor to zero)
∴x=2 or x=1
∴2 and 1 are the roots of x ^2 −3x+2=0

It would be 100 since it it the closest 100
(X+8)^2+(y-15)^2=289 would be the equation to the circle
Answer:
Approx 61.554 feet
Step-by-step explanation:
Since we are dealing with the opposite and adjacent sides, we will use tangent as our ratio.
Since the angle of elevation is 72 degrees, the left side of our equation is 
.
The right side of the equation is opposite over adjacent.
Set these equal to each other.
Simplify.
x is approximately 61.554.
