Answer:

(n- 2/3)²

Step-by-step explanation:

  • <em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>

We have:

  • n² - 4n/3

It can be put as:

  • n² -2×n×2/3

Here we consider n = a and -2/3 = b, then

  • b²= (-2/3)²= 4/9

Now we add 4/9 to a given binomial to make it perfect square:

  • n² - 2×n×3/2 + 4/9= (n- 2/3)²

So, added 4/9 and got a perfect square (n- 2/3)²

Match the following equation to the correct situation.
ANTONII [103]

Answer:

A.  Last month's electricity bill was 5.4 kW-h less than 30% of this month's bill.

Step-by-step explanation:

The given expression is:

30\%(b-18)=30\%b-5.4

The above expression tells us that 30% is of the quantity 'b' and 5.4 is being subtracted from the result of the percentage.

Choice A:

If we consider the present month's bill as 'b'. Then 30% of present month's bill can be represented as 30% of b = 30%b.

Now, if the previous month's bill is 5.4 kW-h less than 30% of this month's bill, then this statement can be represented as:

Previous bill = 30% of Current bill - 5.4 = 30\%b-5.4

Hence, choice A justifies the given expression.

Choice B:

The expression for choice B could be number of songs available for download from 30% of  'b' artists is 30%b.

Choice C:

5.4 speeches doesn't make any sense.

Choice D:

5.4 less than 'b' bowls mean b-5.4. Now, 30% of this is 30%(b-5.4)=30%b-30%(5.4).

This is also not the correct expression.

Therefore, only choice A is the correct justification of the given expression.

levacccp [35]

The number of rows will be a divisor of 550 such that the quotient is 3 more.

... 550 = 1×550 = 2×275 ≈ 5×110 = 10×55 = 11×50 = 22×25

Factors 22 and 25 differ by 3.

The number of rows of seats is 22.

_____

The number of seats in a row is 25.
