Answer:

x = 4

Step-by-step explanation:

Given:

(√x + 2)(√x - 2) = 0

Required:

Find x

SOLUTION:

√x(√x - 2) + 2(√x - 2) = 0 (distributive property)

x - 2√x + 2√x - 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

The figure below shows two parallel lines intersected by a third line. What is the value of x

lisabon 2012 [21]

Answer:

$x = 20$

Step-by-step explanation:

The two angles given in the diagram are alternate interior angles. Alternate interior angles are congruent. Therefore:

(4x)° = (x + 60)°

Use the equation to solve for the value of x

$4x = x + 60$

Subtract x from both sides

$4x - x = x + 60 - x$

$3x = 60$

Divide both sides by 3

$\frac{3x}{3} = \frac{60}{3}$

$x = 20$

Solve -x > 8 or -x < 4.

nevsk [136]

Answer:

x<−8 or x>−4

Step-by-step explanation:

−x>8 or −x<4

We know either −x>8 or −x<4

−x>8(Possibility 1)

−x

−1

(Divide both sides by -1)

x<−8

−x<4(Possibility 2)

−x

−1

(Divide both sides by -1)

x>−4

For the equation: 3x+1=2x+7 what are the 1 st and 2 nd opposite operations?

qaws [65]

Answer:

Step-by-step explanation:

3x +1 = 2x +7 subtract 1 from both sides ( first)

3x +1 -1 = 2x + 7 -1

3x = 2x + 6 subtract 2x brom both sides (second)

3x -2x = 2x -2x +6

5x = 6
