You can take a six out of both factors, 6(3 + x )

so the length would be 6 and the width would be (3+x)

Solve the system using elimination. 2x – 2y = –8 x + 2y = –1 pls help me -w-

padilas [110]

Answer:

(- 3, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 2y = - 8 → (1)

x + 2y = - 1 → (2)

Adding the 2 equations will eliminate the y- term, that is

3x = - 9 ( divide both sides by 3 )

x = - 3

Substitute x = - 3 into either of the 2 equations and evaluate for y

Substituting into (2)

- 3 + 2y = - 1 ( add 3 to both sides )

2y = 2 ( divide both sides by 2 )

y = 1

Solution is (- 3, 1 )

If Tanø =a/b Find the value of sinø+cosø/sinø-cosø

inysia [295]

Answer:

$\frac{b+a}{b-a}$

Step-by-step explanation:

Tan θ = $\frac{perpendicular}{base}$ = $\frac{b}{a}$

So, Perpendicular = b, base = a

<em><u>Finding hypotenuse by Pythagorean Theorem:</u></em>

$c^2 = a^2+b^2$

=> So, <u><em>hypotenuse = c</em></u>

Sin θ = $\frac{perpendicular}{hypotenuse}= \frac{b}{c}$

Cos θ = $\frac{base}{hypotenuse}= \frac{a}{c}$

So, <u><em>Now finding </em></u> $\frac{sin\theta+cos\theta}{sin\theta-cos\theta}$

=> $\frac{b}{c} + \frac{a}{c}$ ÷ $\frac{b}{c} - \frac{a}{c}$

=> $\frac{b+a}{c}$ ÷ $\frac{b-a}{c}$

=> $\frac{b+a}{c} * \frac{c}{b-a}$

=> $\frac{b+a}{b-a}$
