-19+3x-11+2x=2

-19-11+3x+2x= 2

-30+5x= 2

Move -30 to other side. Sign changes from -30 to +30 .

-30+30+5x= 2+30

5x= 32

Divide by 5

5x/5= 32/5

Cross out 5 and 5 , divide by 5. Becomes : x= 32/5

Can someone help me please.​
wolverine [178]

Answer:

  a=\sqrt{33}

The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.

  a² = 7² -4²

  a² = 49 -16 = 33

  a = √33
