8+12+8=0

28=0

x2+6x+8=0

-4(2)+6(2)+8=0

8+12+8=0

28=0

x2+6x+8=0

-8(2)+6(-1)+8=0

-16-6+8

A triangle has side lengths measuring 2x + 2 ft x + 3 ft, and
Marta_Voda [28]

Answer:

3x+5 < n < x-1

Step-by-step explanation:

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

so

Applying the Triangle Inequality Theorem

1) (2x+2)+(x+3) > n

solve for n

3x+5> n

Rewrite

n

2) (x+3)+n> 2x+2

n> x-1

therefore

3x+5 < n < x-1
