The square root of 195 is 13. 195 squared (195×195) is 38,025. I do not know which way you needed it but I put both situations just in case.
(x+7)(x+3) so therefore you set each equation = 0...
x + 7 = 0
x + 3= 0
and solve
x = -3
x = -7
The answer is 2 cause you have to do the asides individually
Answer: $0.3
Step-by-step explanation:
Given
The owner buys 144 pens for $28.80 i.e. each pen costs
![\dfrac{28.80}{144}=\$0.2](https://tex.z-dn.net/?f=%5Cdfrac%7B28.80%7D%7B144%7D%3D%5C%240.2)
owner sells the pen at $0.4 i.e. price marked up by
![\Rightarrow \dfrac{0.4-0.2}{0.2}\times 100=100\%](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B0.4-0.2%7D%7B0.2%7D%5Ctimes%20100%3D100%5C%25)
So, the claim of the owner is incorrect
The actual increase in the price to get 50% markup
![\Rightarrow 0.2\times (1+0.5)=\$0.3](https://tex.z-dn.net/?f=%5CRightarrow%200.2%5Ctimes%20%281%2B0.5%29%3D%5C%240.3)
Uhhhh I don't think that the correct answer.
First, find the gradient of the line segment.
Gradient = Rise/Run = (2-6)/(2-5) = 4/3.
Since the other line segment is parallel to this line segment, their gradients are the same.
That means (-2+4)/(x-5) = 4/3.
2/(x-5) = 4/3
It is obvious x = 6.5
