x^2+6x-5=0
x^2=2x
2x+6x-5=0
2x+6x=8x
8x-5=0
+5 +5
(if you don’t know what I’m doing here is that I’m removing the negative 5 by putting a positive 5 since both of them make 0. Also the “x” always stay alone and the unit stays as the unit)
(I putted the positive under the 0 because what u do to the unit you need to do the same thing with the other.)
8x/8=5/8
(If ur lost here it means dividing.)
The answer
X=0.625
(btw I’m not really sure if this is right so um don’t really trust me in this lol)
Answer:
Step-by-step explanation:
The equation for the area of a circle is A=
.
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
Because when you're working with real wood and tools and glass, there's
no such thing as negative length.
One of the square roots of every number is negative. When you're working with
a real window, the area still has two square roots, but you ignore the negative
one, because it has no physical significance in the real world and it can't help
you, so it's no good for anything.
