Hello salvadorbea340!

$\huge \boxed{\mathfrak{Question} \downarrow}$

- (6y - 4) + (6y - 4) - ( - 2)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

-(6y-4)+(6y-4)-(-2)

Firstly, let's open the brackets of the 1st term, i.e. - (6y - 4).

$-( 6y - 4) \\ = \underline{\underline{- 6y + 4}}$

Now, the 2nd term [ (6y - 4) ].

$+ ( 6y - 4) \\ = \underline{\underline{ + 6y - 4}}$

Now, the 3rd term ⇨ - (- 2)

$-( - 2) \\ = \underline{\underline{ + 2}}$

Now, let's bring the equation together.

$- (6y - 4) + (6y - 4) - ( - 2) \\ = - 6y + 4 + 6y - 4 + 2$

Now, let's solve the equation.

Firstly, bring the like terms together.

$- 6y + 4 + 6y - 4 + 2 \\ = - 6y + 6y + 4 - 4 + 2$

Now cancel out -6y & +6y and 4 & -4 as they make 0.

$- 6y + 6y + 4 - 4 + 2 \\ = \bcancel{- 6y }+ \bcancel{6y} + \bcancel{ \: \: 4 } \: \: - \bcancel{ \: 4 }+ 2 \\ = 0 + 2 \\ = 2$

And, the only number left is 2. So our answer is 2.

$= \large\boxed{\boxed{ 2}}$

Answer from: Quest

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
