When a quadratic equation ax^2+bx+c has a double root, the discriminant,
D=b^2-4ac=0
Here
a=2,
b=b,
c=18
and
D=b^2-4ac=b^2-4*2*18=0
solve for b
b^2-144=0
=> b= ± sqrt(144)= ± 12
So in order that the given equation has double roots, the possible values of b are ± 12.
Lentgh * width = area so, 3.5*9 right?
-12/6+2
=-12/6+2/1
=-2/1+2/1
=-2+2/1
=0
From looking at that equation you put this is my solution.
Answer:
38
Step-by-step explanation:
Line KP is equal to 180 degrees.
The square on angle OLM means that angle is equal to 90 degrees.
Let angle PLO be represented as x.
That would make our equation be 52 + 90 + x = 180.
Start simplifying down to get x by itself.
180 - 90 = 90
52 + x = 90
90 - 52 = 38
x = 38
