$16 {x}^{2} + 9 {y}^{2} = (4x + 3y)(4x - 4y)$
No "i" is needed unless less you take the square root of a negative number.

The locations specified in the order regarding the shape will be B. longest side AC; smallest angle ∠C.

<h3>How to express the information?</h3>

From the information given, in the triangle where A = 59°, B is unknown, and C = 41°. Therefore, the value of B will be:

= 180° - (59° + 41°)

= 180° - 100°

= 80°

Therefore, the locations specified in the order regarding the shape will be longest side AC; smallest angle ∠C.

In conclusion, the correct option is B.

Sin α = 21/29, α lies in quadrant II, and cos β = 15/17, β lies in quadrant I Find sin (α - β).

Sever21 [200]

$\sin(\alpha-\beta)=\sin\alpha\cos\beta-\cos\alpha\sin\beta$

$\sin\alpha=\dfrac{21}{29}\implies \cos^2\alpha=1-\sin^2\alpha=\dfrac{400}{841}$

Since $\alpha$ lies in quadrant II, we have $\cos\alpha$ , so

$\cos\alpha=-\sqrt{\dfrac{400}{841}}=-\dfrac{20}{29}$

$\cos\beta=\dfrac{15}{17}\implies\sin^2\beta=1-\cos^2\beta=\dfrac{64}{289}$

$\beta$ lies in quadrant I, so $\sin\beta>0$ and

$\sin\beta=\sqrt{\dfrac{64}{289}}=\dfrac8{17}$

So

$\sin(\alpha-\beta)=\dfrac{21}{29}\dfrac{15}{17}-\left(-\dfrac{20}{29}\right)\dfrac8{17}=\dfrac{475}{493}$

Suppose we have a generic equation of the form:
$ax ^ 2 + by ^ 2 + ax ^ 2 + cx + dy = f
$

1) The first thing you must do to complete squares is to group similar terms of the form:
$ax ^ 2 + cx + by ^ 2 + dy = f
$

2) The second step is to complete the squares.

3) The third step is factor the quadratic equation

4) The fourth step is to identify the center and the radius

Answer:
the first step in finding the center of the circle by completing the square is:
C group like terms

What is the zero of the equation -4x -12y = 32? <br> PLEASE HELP!!!!

Julli [10]

Answer:

x = - 8

Step-by-step explanation:

To find the zero, let y = 0 in the equation and solve for x

- 4x - 12(0) = 32 , that is

- 4x = 32 ( divide both sides by - 4 )

x = - 8
