8 0

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)

Answer: 5x - 1 = -6

Step-by-Step Explanation:

We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have <u>5x</u> as a start of the equation. We have <u>-1</u> on the same side as well.

Alright, so on the other side- we have Six symbols of "-1".

That concludes to... <u>-6</u>. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. <u>5x - 1 = -6.</u>

Arisa [49]

Answer:

  2a +b

The rule for logarithms is ...

  log(xy) = log(x) +log(y)

__

Applying this to the given problem, we have ...

  log(12) = log(2×2×3)

  = log(2) +log(2) +log(3)

  = a + a + b

  = 2a +b
