hello could you please help me with this math problem with full explanation which I am unable to solve? Thank you.

14 cm

Step-by-step explanation:

from the right triangle we know that:

- A leg is 8 cm

- B leg is 11 cm

- angle between A and B leg is 90'

If we have one angle which is 90' we can use the following formula:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
