Answer:

x = 2 $\sqrt{35}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + b² = a² , that is

x² + 2² = 12²

x² + 4 = 144 ( subtract 4 from both sides )

x² = 140 ( take the square root of both sides )

x = $\sqrt{140}$ = $\sqrt{4(35)}$ = 2 $\sqrt{35}$

Kipish [7]

$180\ minutes\ \ \ \rightarrow\ \ \ 252\ balloons\\\\1\ minute\ \ \ \rightarrow\ \ \ x\ balloons\\\\x\cdot 180=1\cdot 252\ \ \ \Rightarrow\ \ \ x= \frac{252}{180}= \frac{36\cdot7}{36\cdot5} = \frac{7}{5} =1.4\\\\Ans.\ \ 1.4\ balloons\ per\ one\ minute.\\\\-----------------\\\\ 1\ minute\ \ \ \rightarrow\ \ \ 1.4\ balloons\\\\10\ minutes\ \ \ \rightarrow\ \ \ x\ balloons\\\\x\cdot 1=10\cdot1.4\\\\x=14\\\\Ans.\ \ 14\ balloons\ per\ 10\ minutes.$
