Solve for x in the equation x squared + 2 x + 1 = 17.

Papessa [141]

Answer:

$x = - 1 + \sqrt{17}\\and\\x = - 1 - \sqrt{17}\\$

Step-by-step explanation:

given equation

$x^2 +2x +1 = 17$

subtracting 17 from both sides

$x^2 +2x +1 = 17\\x^2 +2x +1 -17= 17-17\\x^2 +2x - 16 = 0\\$

the solution for quadratic equation

$ax^2 + bx + c = 0$ is given by

x = $x = -b + \sqrt{b^2 - 4ac} /2a \\\\and \ \\-b - \sqrt{b^2 - 4ac} /2a$

________________________________

in our problem

a = 1

b = 2

c = -16

$x =( -2 + \sqrt{2^2 - 4*1*-16}) /2*1 \\x =( -2 + \sqrt{4 + 64}) /2\\x =( -2 + \sqrt{68} )/2\\x = ( -2 + \sqrt{4*17} )/2\\x = ( -2 + 2\sqrt{17} )/2\\x = - 1 + \sqrt{17}\\and\\\\x = - 1 - \sqrt{17}\\$

thus value of x is

$x = - 1 + \sqrt{17}\\and\\x = - 1 - \sqrt{17}\\$

a wooden fruit crate will hold 62 pounds of fruit. the crate already has 18 pounds of fruit in it. which inequality represents t

tatuchka [14]

Answer:

$p + 18 \leq 62$

Step-by-step explanation:

Given

$Total = 62\ lb$

$Current = 18\ lb$

Required

Write an inequality to represent the scenario?

Represent the additional number of pounds with p.

When p is added to the current pounds, the weight must be less than or equal to the total possible weights

In other words:

$p + current \leq total$

Substitute values for current and total

$p + 18 \leq 62$

Hence, the inequality that describes the scenario is: $p + 18 \leq 62$
