By definition, the circumference is given by:
C = 2 * pi * R
Where,
R: Radio
Substituting values we have:
C = 2 * pi * (27/2)
C = 84.82300165 in
Round to the nearest whole number:
C = 85 in
Answer:
The circumference of the wheel is:
B. about 85 inches
23,009,040 = 2.300904 x 107
Don't you see that y is a stranger. So group it -y(x+8)
<span>The balance just happens to be x(x+8) </span>
<span>So you have these two terms. Take the common factor out. </span>
<span>(x+8) (x-y) now that's the answer. Easy ... </span>
Answer:
Step-by-step explanation:
Y=2x-7, y=5x+4 goes in one solution
Y=-2x+3, y=2x-1 goes in one solution
Y=5x+4,y=5x-2 goes in no solution
Y=-2x+3,y=1/2x-7 goes in one solution
3y=-12+6,y=-4x+2 goes in infinitely many solutions
Move constant to the right-hand side and change its sign
2x^2 + 8 = -2 + 7
-2 + 7 = 5
Divide both sides of the equation by
x^2 + 4x = 5/2
Add (4/2^2) to both sides of the equation
x^2 + 4x + (4/2)^2 = 5/2 + (4/2)^2
factor the expression
(x + 4/2)^2 = 13/2
reduce the fraction by 2
(x + 2)^2 = 13/2
now solve equation for x
