I think the question is
Find the value of c so that (x-5) is a factor of the polynomial
The other factor is going to be some quadratic. We can say a few things about its coefficients but let's start by saying in general it's
Equating respective coefficients,
so we get
Answer: -37

Answer: 9x+4=50
Step-by-step explanation:
In this case, we're looking at how many you can buy, not how many CD's you own.
<span>tan(15) =
sin(15) / cos(15) =
sin(45 - 30) / cos(45 - 30) =
[ sin(45)cos(30) - sin(30)cos(45) ] / [ cos(45)cos(30) + sin(45)sin(30)]
Since sin(45) = cos(45) = √2/2, you can just factor that out from the top and bottom
[ cos(30) - sin(30) ] / [ cos(30) + sin(30)]
[ √3/2 - 1/2 ] / [ √3/2 + 1/2]
(√3 - 1) / (√3 + 1)
(√3 - 1)^2 / (√3+1)(√3 - 1)
(√3 - 1)^2 / (3 - 1)
(3 - 2√3 +1) / 2
2 - √3
There's also a formula for tan(a-b), but I couldn't remember it off hand.</span>
I hope this helps you
Euclid
h^2=4.6
h=2 square root of 6
h^2+6^2=base^2
24+36=base^2
base=2square root of 15
h^2+4^2=height^2
24+16=height^2
height=2 square root of 10
