Answer:

A) T = -1.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10t+4−2t=2−2(t+4)

10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)

10t+4+−2t=2+−2t+−8

(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)

8t+4=−2t+−6

8t+4=−2t−6

Step 2: Add 2t to both sides.

8t+4+2t=−2t−6+2t

10t+4=−6

Step 3: Subtract 4 from both sides.

10t+4−4=−6−4

10t=−10

Step 4: Divide both sides by 10.

Hope this helps!

Solve the quadratic.<br><br><br> 4x^2+4-20=0<br><br><br><br><br> brainlist if you explain
frez [133]

Answer:

  • x = -1/2(1 +√21) ≈ -2.79129
  • x = -1/2(1 -√21) ≈ 1.79129

Step-by-step explanation:

We assume the middle term is supposed to be 4x.

We can remove a common factor of 4 to simplify this a bit.

  x^2 +x -5 = 0

This is of the form

  ax^2 +bx +c = 0

where a=1, b=1, c=-5.

__

The <em>quadratic formula</em> gives the solutions as ...

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Filling in the given coefficients, we have ...

  x = (-1 ±√(1^2 -4·1·(-5)))/(2·1)

  x = (-1±√21)/2

The solutions are x = -1/2(1 +√21) and -1/2(1 -√21).

_____

<em>If what you wrote is what you intend</em>, then the equation simplifies to 4x^2 -16 = 0.

Dividing by 4 and factoring the difference of squares gives ...

  x^2 -4 = 0

  (x -2)(x +2) = 0

These factors are zero (hence their product is 0) for the values x = 2 and x = -2.

The solutions are x=2 and x=-2.
