For this case we have the following polynomial:
To find the value of c that completes the square, we use the following equation:
Where,
- <em>b: coefficient of the variable of degree 1
</em>
Substituting values we have:
Answer:
the value of c that completes the square is:
Answer:
The width of the rectangle is the same as the length of the cylinder (h). The area of each of the two circles is \\ (\\pi r^2\\) and the area of the rectangle is \\ (2 \\pi r times h\\).
Step-by-step explanation:
Answer:
is the second answer 2x+1/x-1
Step-by-step explanation:
from (2)
x-y=2
y=x-2 (3)
subs (3) into (1)
x²-2x+(x-2)=8
x²-2x+X-10=0
x²+x-10=0
quadratic formula
x= (-1±√1²-4×1×(-10))/2(1)
X=( -1±√41)/2
X=(-1+√41)/2
=
x=(-1-√41)/2
=
