Answer:

The common difference is \frac{1}{5} or 0.2

Step-by-step explanation:

Given:

Arithmetic Sequence -2, -1 4/5, -1 3/5, -1 2/5,

First term      = a₁ = -2

Second term = a₂ = \frac{-9}{5}

Third term     = a₃ = \frac{-8}{5}

Fourth term = a₄ = \frac{-7}{5}

To Find:

Common Difference = d = ?

Solution:

Formula for Common Difference d ,\textrm{common difference}= \textrm{Second Term} -\textrm{First Term}=\textrm{Third Term}-\textrm{Second Term}

\textrm{common difference} = a_{2}- a_{1}= a_{3}- a_{2}=a_{4}- a_{3}

∴ d = \frac{-9}{5}-(-2)\\d=\frac{-9}{5}+2\\d=\frac{1}{5}\\ \therefore d =0.2\\

The common difference is \frac{1}{5} or 0.2

Answer:

6

Step-by-step explanation:

Hello,

The two triangles are <u>similar</u> and x is <u>positive</u>, <u>different from 0</u>, so we can write.

\dfrac{x}{9}=\dfrac{12}{x}\\\\x^2=12\times 9\\\\ x = \sqrt{4\times 3 \times 9}=2\times 3 \times \sqrt{3}\\\\ \boxed{\sf \bf x=6\sqrt{3} }

Thanks
