A triangle has side lengths measuring 2x + 2 ft, x + 3 ft, and n ft. Which expression represents the possible values of n, in fe

cluponka [151]

Answer:

$x-1$

Step-by-step explanation:

If a, b and c are the lengths of the triangle's sides, then

$a+b>c,\\ \\a+c>b,\\ \\b+c>a.$

Since

$a=2x+2,\\ \\b=x+3,\\ \\z=n,$

then

$2x+2+x+3>n\Rightarrow nx+3\Rightarrow n>1-x,\\ \\x+3+n>2x+2\Rightarrow n>x-1.$

Thus,

$x-1$

Write any two quadratic equations.

Thepotemich [5.8K]

To find:

Any two quadratic equations.

Solution:

The general form of a quadratic equation is:

$ax^2+bx+c=0$

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

$1x^2+1x+1=0$

$x^2+x+1=0$

One quadratic equation is $x^2+x+1=0$ .

For a=3,b=-1,c=5, we get

$3x^2+(-1)x+5=0$

$3x^2-x+5=0$

Therefore, the two quadratic equations are $x^2+x+1=0$ and $3x^2-x+5=0$ .
