Answer with explanation:

We want , (x+5) to be a Common factor of the rational expression

     =\frac{x^2+6 x+14}{x+5}

So, if we write

 x^2+6 x+14=x²+6 x+ 5+9

So, to get (x+5) as a common factor, we should subtract 9 from the Quadratic expression.

    \Rightarrow \frac{x^2+6 x+14-9}{x+5}\\\\=\frac{x^2+6 x+5}{x+5}\\\\=\frac{x^2+5 x+x+5}{x+5}\\\\=\frac{x \times (x+5)+1 \times (x+5)}{x+5}\\\\=\frac{(x+5)(x+1)}{x+5}\\\\=x+1

⇒Subtract ,9 from the Numerator,That is constant term that we need in Numerator = -9

The figure has 5 sides, so it must be a pentagon. Pentagon’s interior angles sum up to 540°.

Therefore:

132+90+3x=540

222+3x=540

3x=318

x=106

Checking work, where x=106

222+3(106)=540.

So x°=106°

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
Igoryamba

Answer:

A

Step-by-step explanation:

Joint variation is given by:

y=kxz

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

360=k(4)(10)

Solving for k:

40k=360\Rightarrow k=9

Therefore, our equation is:

y=9xz

Then when x = 5 and z = 12:

y=9(5)(12)=540

The answer is A.

Let x = a + bi and y = c + di and z = f + gi
ikadub [295]
True statements:
a) x + y = y + x  ⇒ commutative property of addition
b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication
d) (x + y) + z = x + (y + z) ⇒ associative property of addition

False statements:
c) x - y = y - x  should be: x - y = - y + x
e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
