Factor the four-term polynomial.

Travka [436]

Group like terms , factor out common variable.

(xz+x) + (yz+y)
x(z+1) + y(z+1)

factor out (z+1)

= (z+1)(x+y)
= solution C.

The ratio of the side adjacent am acute angle and the hypotenuse. Adjacent/hypotenuse

diamong [38]

Answer: The answer is cosine of that acute angle.

Step-by-step explanation: We are to find the ratio of the adjacent side of an acute angle to the hypotenuse.

In the attached figure, we draw a right-angled triangle ABC, where ∠ABC is a right angle, and ∠ACB is an acute angle.

Now, side adjacent to ∠ACB is BC, which is the base with respect to this particular angle, and AC is the hypotenuse.

Now, the ratio is given by

$\dfrac{\textup{adjacent side}}{\textup{hypotenuse}}=\dfrac{BC}{AC}=\dfrac{\textup{base}}{\textup{hypotenuse}}=\cos\textup{ of angle }ACB.$

Thus, the ratio is cosine of the acute angle.

Which technique is most appropriate to use to solve each equation? Drag the name of the technique into the box to match each equ

faltersainse [42]

(x + 3) (x + 2) = 0
To solve it, the most appropriate technique is:
1.) zero product property
The solutions are:
(x + 3) = 0
x = -3
(x + 2) = 0
x = -2

x² + 6 = 31
To solve it, the most appropriate technique is:
2.) square root property
x² = 31-6
x² = 25
x = +/- root (25)
x = +/- 5
The solutions are:
x = 5
x = -5

Plzzzzzzzzzzzzzzzzzzzzz help show your work <br><br><br> - 9/2+-8/13

S_A_V [24]

Answer:

-133/26

Step-by-step explanation:

-9/2 + -8/13

First find a common domintor.

26 will be a common domintor.

2 × 13=26 so multiply -9 by 13= -117

13×2=26 so multiply -8 by 2= -16

-117/26 + -16/26 = -133/26
