Enter the correct value so that each expression is a perfect square trinomial
myrzilka [38]

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}.

Could someone please help me with this problem! I would really appreciate your help, a through explanation, how to work the prob
Ulleksa [173]

-(-3 - 2) + (-5)

First solve inside the parentheses.

-(-5) + (-5)

Note the double negative sign in the front changes the -5 to a positive 5. Now your equation is:

5 + (-5) which is the same as 5 - 5.

So your answer is 0.

Answer:

x = 15

Step-by-step explanation:

x/3 + 10 =15

Subtract 10 from each side

x/3+10-10 =15-10

x/3 = 5

Multiply each side by 3

x/3*3 = 5*3

x=15
