The height of a triangle is 2ft less than the base x. The area is 144ft2

Step-by-step explanation:

Area=1/2×b×h

144=1/2×x×(x-2)

288=x^2-2x

x^2-2x-288

x^2-18x+16x-288

x (x-18)+16(x-18)

(x+16)(x-18)=0

Therefore base is 18 as length cant be negetive.

base is 18

and hieght is 16.

i think it is c, not positive though

step-by-step explanation:

25 questions , because they start with 100.
