Which equations are true for x = –2 and x = 2? Select two options
fomenos

Answer:

Number 1 and Number 4

Step-by-step explanation:

By factoring, you can figure out the roots (x = -2 or x = 2)...

1. x^2 - 4 = 0

--> (x + 2)(x - 2) = 0

--> x = -2, x = 2

2. x^2 + 4 = 0

--> factors weirdly, so I won't write it. You'd have to use the quadratic formula.

3. 3x^2 + 12 = 0

--> 3 (x^2 + 4) = 0

--> factors weirdly (same as above)

4. 4x^2 - 16 = 0

--> 4 (x^2 - 4) = 0

--> 4 (x+2) (x-2) = 0

--> x = -2, x = 2

5. 2 (x-2) 2 = 0

--> x = 2

Find the value of x, rounded to the nearest tenth.<br>​
Step2247 [10]

Answer:

x = 18

Step-by-step explanation:

Given two intersecting chords inside a circle, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

7x = 21 × 6 = 126 ( divide both sides by 7 )

x = 18

Answer:

Numbers\ are\ 58\ and\ 51.

Step-by-step explanation:

The the numbers are x\ and\ y.

<em>Difference:</em>

<em></em>Difference\ of\ numbers=7\\\\x-y=7....................eq(1)<em></em>

<em>Sum:</em>

<em></em>Sum\ of\ numbers=109\\\\x+y=109...........................eq(2)<em></em>

<em></em>

Solve eq(1) and eq(2).

eq(1)+eq(2)\\\\x-y+x+y=7+109\\\\2x=116\\\\x=58\\\\Now\ from\ equation\ 1\\\\x-y=7\\\\y=x-7\\\\y=58-7\\\\y=51
