Answer:

(7x+6    )  ( x -2   )

Step-by-step explanation:

7x^2 -8x-12

(7x    )  ( x    )

What are the factors of -12

-1*12       1 * -12

-2*6          2 * -6

-3*4           3 * -4

Something * 7 + something = -8

We need to fill in   with the factors

-2 * 7 + 6 = -8

-14 -6 = -8  True

7x^2 -8x-12

Split the second term 7x^2 - 8x - 12 into two terms

7x^2 + 6x - 14x - 12

Factor out common terms in the first two terms, then in the last two terms

x(7x + 6) - 2(7x + 6)

Factor out the common term; 7x + 6

<u>(7x + 6)(x - 2) </u>

Use law of sines or law of cosines to find the length of side AB Please show work !!
scoray [572]

Answer:

AB = 11.3

Step-by-step explanation:

Given

The attached triangle

Required

Length AB

To do this, we make use of sine law which is represented as:

\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}

So, we have:

\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}

Make AB the subject

AB = \frac{15}{\sin(70)} * \sin(45)

AB = \frac{15}{0.9397} *0.7071

AB = 11.3
