Enter the correct value so that each expression is a perfect square trinomial

Mathematics
1 answer:
myrzilka [38]3 years ago
5 0

Answer:

Step-by-step explanation:

1). x² - 10x + a²

  By using the formula of (a - b)² = a² - 2ab + b²

  x² - 2(5)x + a²

  Therefore, for a perfect square of the expression a should be equal to 5.

  Therefore, (x² - 10x + 25) will be the answer.

2). x² + 2ax + 36

  = x² + 2(a)x + 6²

  For a perfect square of the given expression value of a should be 6.

   x² + 2(a)x + 6² = x² + 2(6)x + 6²

                           = (x + 6)²

  Therefore, x² + 12x + 36 will be the answer.

3). x^{2}+\frac{1}{2}x+a^2

    x^{2}+2(\frac{1}{4})x+a^2

   To make this expression a perfect square,

   a² = (\frac{1}{4})^2

   x^{2}+2(\frac{1}{4})x+(\frac{1}{4})^2 = (x+\frac{1}{4})^2

  Therefore, the missing number will be \frac{1}{16}.

An opera house has a seating capacity of 872 people with each ticket costing 50 Rupees .If the opera house is running for 15 day
Nataly_w [17]

Answer:

654000 Rupees

Step-by-step explanation:

If we assume that the opera house was full every day then it would be 872 x 50 for the price of 1 day

872 x 50 = 43600

We multiple that number by the amount of days open so is would be 43600 x 15

43600 x 15 = 654000

Therefore it will make 654000 Rupees

Algebra II<br> line: 3(x - 2) &gt; 5x + 8
m_a_m_a [10]

Answer:

x < - 7

Step-by-step explanation:

Given

3(x - 2) > 5x + 8 ← distribute parenthesis on left side

3x - 6 > 5x + 8 ( subtract 3x from both sides )

- 6 > 2x + 8 ( subtract 8 from both sides )

- 14 > 2x ( divide both sides by 2 )

- 7 > x, hence

x < - 7
