Mark Bellezza@mark_bellez·7h@Math_World_ b^2 + 144=400, subtract 144 both sides—> b^2=256 so b=Sqrt 256=16 —> 36+144=x^2 —> 180=x^2 so 13.42 cm = xแปล English00052

Mark Bellezza@mark_bellez·8h@MathGuyTFL Add 5 to both sides—> Sqrt(3x)=6, square both sides—> 3x=36, divide both sides by 3 —> x=36/3=12แปล English00056
Mark Bellezza@mark_bellez·8h@Puzzlesonly 41^2-40^2=81 and Sqrt 81=9 so answer is (a) 9แปล English000110

Mark Bellezza@mark_bellez·1d@mathtech789 Add the 5^x s —> 2(5^x)=10, divide both sides by 2 —> 5^x=5 so x=1 so 5^(1+2)=125แปล English00017
Mark Bellezza@mark_bellez·1d@Sam_Axiom factor numerator—> (2a(a-2))/(a-2)=2 —> 2a=2 so a =2/2=1แปล Español00145
