I will give you brainilest! Assuming you had access to strips of any lengths, and you used the 9-inch and 5-inch strips as the first two sides of a triangle, complete the sentences:
The third side can't be (fill in the blank) inches or longer.
The third side can't be (fill in the blank) inches or longer.

step-by-step explanation:

damm bro the struggle

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
