Use Pythagorean's, in figure 1: t^2+12^2=13^2. t=\sqrt(13^2-12^2)=\sqrt(25)=5.
In figure 2: 6^2+9^2=x^2. x=\sqrt(36+81)=\sqrt(117)=3*\sqrt(13).
Well the answer is 13 and cannot be written in simplest form because 1/2 and 1/2 have the same denominator so you add them together and you get 2/2 which is a whole number then you add the other whole numbers but don’t forget the new whole number then add the 5 and you get 13 cm

Option D is correct
2x^3 - 7x^2 + 4x - 3
Step-by-step explanation:
= x(2x^2 - x + 1) -3 (2x^2 - x + 1)
= 2x^3 - x^2 + x - 6x^2 + 3x - 3
= 2x^3 - x^2 - 6x^2 + x + 3x - 3
= <u>2x^3 -7x^2 + 4x -3 (Ans)</u>
