(x+x)^2 × -(x×(-1))=4+x-x^2 <br> solve for x, show work.
Anna71 [15]

Answer:

x = 1

x = -5/8   + i* root( 39)  / 8

or x = -5/8   - i* root( 39)  / 8

Step-by-step explanation:

(x+x)^2 × -(x×(-1))=4+x-x^2

solve for x, show work.

(x+x)^2 ×  -(x×(-1))     =   4+x-x^2

Simplify:

(2x)^2  * (-(-x))  =  4 + x -  x^2

4x*x * (-(-x)) = 4 + x - x*x

4*x*x*x  = 4  + x - x*x

4*x*x*x - 4  =  x *(1 - x)

4* (xxx - 1)  = x * (1- x)

4* (x - 1)*( x*x +x + 1)  =  x (1 - x)

4( xx + x + 1)  = -x

x = 1 is a solution.

4xx + 4x + 4 = -x

4xx + 5x + 4 = 0

x = -5/8  +   root(25 - 4*4*4) / 2*4

x = -5/8   + i* root( 39)  / 8

or x = -5/8   - i* root( 39)  / 8

also x = 1

SVEN [57.7K]
24 feet long :)
All I did was I divided the 36 into 3 equal parts of 12, then doubled the 12 to make that longer piece 24 feet. This 24 foot piece would be twice as long as the other leftover 12 foot piece since 12x2=24

A triangle was dilated by a scale factor of 6. If sin aº
Pavlova-9 [17]

Answer:

24 units

Step-by-step explanation:

A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF?

triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees

15.5 units

24 units

30 units

37.5 units

From the description:

angle D measures a degrees

opposite to angle D is side EF

side DE (which measures 30 units) is the hypotenuse of the triangle.

We also know that

\sin (a) = \frac{4}{5}

\sin (a) = \frac{opposite}{hypotenuse}

From definition:

\sin (a) = \frac{opposite}{hypotenuse}

Replacing:

\frac{4}{5} =\frac{ EF}{DE} \\\\EF = \frac{4}{5} *DE\\\\EF = \frac{4}{5} *30 \\\\= 24 units
