Answer: 4x + 7 - ( x + 1)

Remove the bracket

We get

4x + 7 - x - 1

= 3x + 6

That's option B

What is the range of possible values for x?

Talja [164]

The minimum value for 2x is 0
the maximum value is achieved when A, D and C are collinear and the quadrilateral ABCD becomes an isosceles triangle ABC 
base AB = 52 and vertical angle 2x + 34° 

For the sine law 
(sin 2x)/22 = (sin ADB)/AB 
(sin 34°)/30 = (sin BDC)/BC 

is given that AB = BC, and sin ADC = sin BDC because they are supplementary, so from 
(sin ADC)/AB = (sin BDC)/BC 

it follows 
(sin 2x)/22 = (sin 34°)/30 

sin 2x = 22 (sin 34°)/30 

2x = asin(22 (sin 34°)/30) ≈ 24.2° 

x = 0.5 asin(22 (sin 34°)/30) ≈ 12.1° 

0 < x < 12.1°

The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
__________________________________________________________
Consider choice [A]: $\frac{(3)(4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [A]" .
__________________________________________________________
Consider choice [B]: $\frac{(-3)(4)}{(6)}$ ;
= $\frac{-12}{6}$ ;
= "-2" ; Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________
Consider choice [C]: $\frac{(-3)(-4)}{(6)}$ ;
= $\frac{12}{6}$ ;
= 2 ; "2 ≠ -2" ; so we can rule out: "Choice [C]" .
__________________________________________________________
The correct answer is: [B]: " $\frac{(-3)(4)}{(6)}$ " .
