Answer:
Hope that this is helpful.
Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3

Answer:
25
Step-by-step explanation:
25 has 2 digits
25 is less than 30
25 is odd
2+5 = 7
It is 25.
30 feet is correct. Since a = 3b, the wingspan is 6 inches in the drawing, so it is 6x5 = 30 feet on the plane.
