The difference of the square of a number and 16 is equal to 6 times that number. Find the negative solution.
1 answer:
Answer:
The negative solution is -2
Step-by-step explanation:
Let the number be x
x² - 16 = 6x
Equate the equation to zero (0)
x² - 6x -16 = 0
Factorize
x² + 2x -8x - 16 = 0
x(x + 2) -8(x + 2) = 0
Therefore,
(x-8) (x +2) = 0
x -8 = 0 or x +2 = 0
x = 8 or x = -2
The negative solution is -2

Answer:
The correct answer is,
I'm 100000000% sure.
The area are in the ratio of the squares of corresponding sides.
That is 15^2 : 20^2 = 225:400
so the area of the smaller figure = (225/400) * 64
= 0.5625 * 64
= 36 cm^2 (answer)
