Answer:

Step-by-step explanation:

x2 - 12x+ 35 = x^2 - 7x -5x +35

                   = x ( x-7) - 5(x - 7)

                   = (x-7)(x-5)

<u>ANSWER:  </u>

The factors of the expression x^{2}-12x+35 are (x – 7) and (x – 5).

<u>SOLUTION: </u>

Given, Trinomial expression is x^{2}-12x+35

Trinomial is nothing but an expression or equation having three terms in it.  

Given expression is quadratic expression.

Now, to factorize any quadratic expression we need to write the constant term as product of two numbers, such that sum two number should equal to coefficient of x, in order to take common.

x^{2}-12 x+35

By writing constant as product of two numbers, we get

x^{2}-12 x+5 \times 7

By writing the “x” term as sum of two number coefficients, we get

x^{2}-7 x-5 x+5 \times 7

By taking x and  -5 as common

x(x – 7) –5(x – 7)

By taking (x – 7) as common, the above expression becomes,  

(x – 7)(x – 5)  

Thus factors of the expression X^{2}-12 X+35 are (x – 7) and (x – 5).

Mariulka [41]

9514 1404 393

Answer:

  80.5°

Step-by-step explanation:

The applicable trig function is the tangent.

  Tan = Opposite/Adjacent

In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...

  tan(α) = 324/54

The value of the angle with this tangent is found using the arctangent function:

  α = arctan(324/54) ≈ 80.5°

She should set her binoculars to 80.5°.
