Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0

AnnyKZ [126]

we have

$x^{2}+2x + 1 > 0$

we know that

$x^{2}+2x+1=(x+1)^{2}$

$(x+1)^{2}> 0$

two solutions

<u>first solution </u>

$(x+1)> 0$

$x > -1$

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

$-(x+1)> 0$

$-x-1> 0$

$-x> 1$

$x< -1$

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number $-1$

Americans who are 65 years of age or older make up 12.9% of the total population. If there at 30.3 million american in this age

telo118 [61]

Total population of US is 234.88 million.

Step-by-step explanation:

Given,

Number of people are 65 or older = 30.3 million

This represents 12.9% of total population.

Let,

x represent the total population.

12.9% of x = 30.3 million

$\frac{12.9}{100}x=30.3\ million\\0.129x=30.3\ million$

Dividing both sides by 0.129x

$\frac{0.129x}{0.129}=\frac{30.3}{0.129}\ million\\\\x=234.88\ million$

Total population of US is 234.88 million.

What is this answer? I have no idea. pls help :( will give brainliest

Artist 52 [7]

The answer is B.

Negative numbers are to the far left if you were using a number line, so -1 to the 3rd power is -1. Everything else is positive. 1/4 is the same as 0.25 which is less than positive 1, positive 8.8 is next and the last would be -5 to the 2nd power which is 25.
