Answer:

p=-1

Step-by-step explanation:

3x^2+6x-6=0

Add 6 on both sides

3x^2+6x=6

Divide through by 3

x^2+2x=2

Complete the square on the right side

If a quadratic equation is given by

ax^2+bx+c=0

then c=b/2

x^2+2x=2

c=2/2=1

Adding 1 on both sides

x^2+2x+1=2+1

x^2+x+x+1=3

Combining

x(x+1)+1(x+1)=3

(x+1)(x+1)=3

(x+1)^2=3

p=-1

A piece of wire 23 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral tria

AURORKA [14]

Answer:

For maximum area, all of the wire should be used to construct the square.

The minimum total area is obtained when length of the wire is 10m

Step-by-step explanation:

For maximum, we use the whole length

For minimum,

supposed the x length was used for the square,

the length of the side of the square = x/4m

Area = $\frac{x^{2} }{16}$

For the equilateral triangle, the length of the side = $\frac{23 - x}{3}$

Area = $\frac{\sqrt{3} }{4} a^{2} = \frac{\sqrt{3} }{4} (\frac{23 - x}{3} )^{2}$

Total Area = $\frac{x^{2} }{16}$ + $\frac{\sqrt{3} }{36} (23-x)^{2}$

$\frac{dA}{dx} = \frac{x}{8} - \frac{\sqrt{3} }{18} (23 - x)\\$

$\frac{d^{2}A }{dx^{2} } = \frac{1}{8} + \frac{\sqrt{3} }{18} > 0$ , therefore it is minimum

$\frac{dA}{dx} = 0 \\\\$

$\frac{x}{8} - \frac{\sqrt{3} }{18} (23 - x) = 0\\$

x = 10.00m

Think of a number, when 1/15 of this number is subtracted from 2/5 of the same number, the answer is 5/9. What number did I thin

Licemer1 [7]

The you thought number of likely is mathematically given as

x=-5/3

Question Parameters:

when 1/15 of this number is subtracted from 2/5 of the same number,

the answer is 5/9.

Generally the equation for the Statement is mathematically given as

1/15x-2/5x=5/9

Therefore

x=-5/3
