HL Theorem would prove these two triangles are congruent.
Answer:
A=150
Step-by-step explanation:
you can split the shape into a square and triangle. the square's area is 15 x 6 = 90. the triangles area is (1/2) (14-6) (15)= 60. then you add them together and get 150
Answer: 378

Work Shown:
f(x) = x^2 - 3x
f(x) = ( x )^2 - 3*( x )
f(-18) = ( -18 )^2 - 3*( -18 ) ... replace every x with -18; now use PEMDAS
f(-18) = 324 - 3*( -18 )
f(-18) = 324 + 54
f(-18) = 378
