In triangle ABC ,AD= 9cm and BC =12 cm .The area of triangle ABC is equal to ?​

I assume AD means AB? Well in that case then since AB = 9, then we know one side is 9. if BC is 12, then we know that ABC has a hypotenus of 13 less AC is not the longest side, of which then then missing side length is √63. If AC is the hypotenus, then the triangle has an area of 54. if the hypotenus is 12, then the area is going to be 4.5√63

69

step-by-step explanation:

-7

step-by-step explanation:

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

= (x + 9)^2 - 7.

so q = -7.
