(9p-5q)^2=can anyone plss answers this

DIA [1.3K]

Step-by-step explanation:

${(9p - 5q)}^{2}$

Hence according to ,

${(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2}$

So,

${(9p)}^{2} - 2 \times 9p \times 5q + {(5q)}^{2}$

$81 {p}^{2} - 90pq + 25 {q}^{2} (ans)$

Write a rational number in fraction form that is equivalent to -1.\overline{5}

lorasvet [3.4K]

Answer:

$\dfrac{-14}{9}$ .

Step-by-step explanation:

The given number is $-1.\overline{5}$ .

We need to find a rational number in fraction form that is equivalent to given number.

Let $x=-1.\overline{5}$

$x=-1.555...$ ...(1)

Multiply both sides by 10.

$10x=-15.555...$ ...(2)

Subtracting (1) from (2), we get

$10x-x=-15.555...-(-1.555...)$

$9x=-14$

Divide both sides by 9.

$x=\dfrac{-14}{9}$

Therefore, the required rational number is $\dfrac{-14}{9}$ .
