Answer:

  • Option D

Step-by-step explanation:

  • -(x+1)²- 4 = 0
  • (x+1)² =  - 4
  • x + 1 = ± √-4
  • x = -1 ± 2i

Correct choice is D

Answer:

D

Step-by-step explanation:

Given

- (x + 1)² - 4 = 0 ( add 4 to both sides )

- (x + 1)² = 4 ( multiply both sides by - 1 )

(x + 1)² = - 4 ( take the square root of both sides )

x + 1 = ± \sqrt{-4} = ± 2i ( subtract 1 from both sides )

x = - 1 ± 2i , then

x = - 1 + 2i, x = - 1 - 2i → D

Solve for x. <br> (parallelogram)
victus00 [196]

The value of x is 55°

Step-by-step explanation:

Given figure is a parallelogram.

In a parallelogram, the opposite sides are equal and parallel and the opposite angles are equal.

This means that,

in the given parallelogram

m∠A=m∠C=x°

m∠B=m∠D=(2x+15)°

The sum of interior angles of a parallelogram is 360 degrees.

So,

m∠A+m∠B+m∠C+m∠D=360°

Putting the values of angles

x+(2x+15)+x+(2x+15)=360\\x+2x+15+x+2x+15=360\\6x+30=360\\Subtracting\ 30\ from\ both\ sides\\6x+30-30=360-30\\6x=330\\Dividing\ both\ sides\ by\ 6\\\frac{6x}{6}=\frac{330}{6}\\x=55

The value of x is 55°

Twenty five X squared minus one hundred and forty four
neonofarm [45]

OK.

-- Since it's the difference of two squares,
the factored form of that expression is

                 (5x + 12) (5x - 12) .

-- We don't know the value of the expression
until you tell us the value of 'x'.  And then, if
'x' changes, the value of the expression also
changes, immediately, without any delay.
