Answer:
40.192 centimeters
Step-by-step explanation:
The circumference of a circle can be found using:
c= pi* diameter
First, we must find the diameter. The diameter of a circle is twice it’s radius.
d=2*radius
The radius of the circle is 6.4 centimeters. Substitute 6.4 for the radius.
d=2*6.4
d=12.8
Now we know the diameter. We can substitute 12.8 for diameter in the circumference equation.
c=pi*diameter
c=pi*12.8
We also know we are using 3.14 for pi, so we can substitute 3.14 for pi.
c=3.14*12.8
c=40.192
Use appropriate units: centimeters
c=40.192 centimeters
The circumference is 40.192 centimeters.
A cubic function only has 3 solutions at which x = 0, never 4. For example the function y =
gives the solutions:
x = 0, x = -1 and x = -2
Two angles on a straight line will always equal 180 when combined.
180 - 45 = x
X = 135

Answer:
Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
the answer is -7x +12
Step-by-step explanation:
the question can be solved using BODMAS law
from Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
opening the bracket
4-5x + 3 + 2x - 4x + 5
collecting the like terms we have;
12-7x
therfore ; -7x + 12
