If 15 + x,28 – x, and 29 + x form an arithmetic sequence what is the value of x?

ollegr [7]

Answer:

Step-by-step explanation:

If its an AS it well have a common difference, so 3rd term - 2nd term should = 2nd term - first term:-

29 + x - (28 - x) = 28 - x - (15 + x)

2x + 1 = 13 - 2x

4x = 12

x = 3.

The sequence is

15 + 3, 28-3, 29 + 3

= 18, 25, 32

which is arithmetic with common difference 7.

Solve for x. Use the completing the square method. x² + 8x = 7

AfilCa [17]

Divide the coefficient by 2 then square the quotient.
Add the result to both sides of the equation.

$x^2 + 8x = 7$
$x^2 + 8x + (\frac{8}{2})^2 = 7 + (\frac{8}{2})^2$
$x^2 + 8x + 4^2 = 7 + 4^2$
$x^2 + 8x + 16 = 7 + 16$
$x^2 + 8x + 16 = 23$

Now, factor the left-hand side.

$x^2 + 8x + 16 = 23$
$(x + 4)^2 = 23$

Take the square root of both sides.

$(x + 4)^2 = 23$
$x + 4 = \sqrt{23}$
$x = -4$ ± $\sqrt{23}$
