Answer: He still owns 64% of the Mr.Williams' original parking.
Step-by-step explanation:
Let x = Area of the original parking plot.
First he sold 20% of his lot to neighbor .
Sold plot = 20% of x = 0.20x [Replace 'of' by '×' and divide number by 100 to remove %]
Reminder= x-0.20x= (1-0.20)x=0.80x
Again he sold 20% of the remainder .
Sold plot = 20% of (0.80x) = 0.20 (0.80x)
= 0.16x
Remainder plot = 0.80x-0.16x= 0.64x
Percent of Mr.Williams' original parking lot does he still own = ![\dfrac{0.64x}{x}\times100=64\%](https://tex.z-dn.net/?f=%5Cdfrac%7B0.64x%7D%7Bx%7D%5Ctimes100%3D64%5C%25)
Hence, he still owns 64% of the Mr.Williams' original parking.
Answer:
Step-by-step explanation:
p² + 14p + 49 = p² + 2 * 7p + 7²
Comparing with a² + 2ab + b²,
a= p and b = 7
So 2ab = 2*p*7 = 14 p
So, p² + 14p + 49 is a perfect trinomial
