What is the value of x plz help

Solve for one half on the triangle with height 6 and base would be 4/2 = 2

Use the Pythagorean theorem:

X = sqrt( 6^2 + 2^2)

X = sqrt( 36 + 4)

X = sqrt(40)

The answer is D

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

x² + 11x + 18 < 0  

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

solution: (-9, -2)
