Answer:

{y}  =  6\sqrt{3} \:units

Step-by-step explanation:

By Pythagoras Theorem:

{y}^{2}  =  {(9 + 3)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  =  {(12)}^{2}  -  {(6)}^{2} \\  \\   {y}^{2}  = 144 -  36 \\  \\  {y}^{2}  = 108 \\  \\  {y}  =  \sqrt{108}  \\  \\  {y}  =  \sqrt{36 \times 3}  \\  \\ {y}  =  \sqrt{ {6}^{2}  \times 3}  \\  \\ {y}  =  6\sqrt{3}\:units

Step-by-step explanation:

Dont know if thats o or and zero but I solve it by using o..if it was a zero then comment that so I can redo it anyways heres the explanation

(7nm^5 o^2) × (-3m^3 o^5)^2

7m^5 no^2) ×(-3m^3 o^5) ^2

(7m^5 no^2) × (3m^3 o^5)^2

7m^5 no^2 × (3m^3 o^5) ^2

7m^5 no^2 × 9m^6 o^10

If J = 12 then J/3 + 3 What is J
kolbaska11 [484]
Well, you're given that J=12. I think the extra information is extraneous, unless there's something more that you forgot to add.
Hope I could be of some assistance. :)

Suppose b is any integer. If b mod 12 = 5, then 7b mod 12
Rzqust [24]

The result follows directly from properties of modular arithmetic:

b\equiv5\pmod{12}\implies 7b\equiv35\equiv-1\equiv\boxed{11}\pmod{12}

That is,

b\equiv5\pmod{12}

means we can write b=12n+5 for some integer n. Then

7b=7(12n+5)=12(7n)+35

and taken mod 12, the first term goes away, so

7b\equiv35\pmod{12}

etc
