Answer:
False
Step-by-step explanation:
6*2= 12
So to get common denominators, you would need to divide 5/12 by 2 OF multiply 2/6 by 2
For the sake of ease just multiply 2/6 by 2, this will equal 4/12 NOT 5/12
Hope this helps! :)
Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
Answer:
