Answer:
153 points
Step-by-step explanation:
Set up a proportion:
34/4 = x/18.
18/4 does not equal a whole number. So, reduce 34/4.
34/4 becomes (when divided by 2 on both the top and the bottom) 17/2.
18/2=9. 9*17=153.
802.11 legacy = 2 Mbps<span>
802.11a = </span>54 Mbps<span>
802.11b = </span>11 Mbps<span>
802.11g = </span><span>54 Mbps</span>
Circumference=2(pi)r or (pi)d
You know that Circumference=113.04
You know that the diameter=2x+4
Plug what you know into the equation and solve for x.
C =(pi) d
113.04=(pi)(2x+4)
Sure
Answer:
x = -2

The steps
Multiply all terms by (x-3)(x+3) and cancel:
x(x+3)+2x(x−3)=18
3x2−3x=18(Simplify both sides of the equation)
3x2−3x−18=18−18(Subtract 18 from both sides)
3x2−3x−18=0
3(x+2)(x−3)=0(Factor left side of equation)
x+2=0 or x−3=0(Set factors equal to 0)
x=−2 or x=3
Check answers. (Plug them in to make sure they work.)
x=−2 (Works in original equation)
x=3 (Doesn't work in original equation)
-.25a-4=4
Add for on both sides
-.25a=8
Divide by -.25
A=
