Answer:

Step-by-step explanation:

First we should solve the problems inside the bracket (a+x). Since a=8 and x=-10, (a+x) = (8+(-10)). (8+(-10))= (8-10). Then it is only a matter of subtraction and multiplication. (8-10)=(-2). Now we have clear numbers instead of variables, so (-3)(-2)=+6 (since two brackets with no sign in between will multiply the contents inside each other together.). I hope this was helpful!

TL;DR: (-3)(a+x)=(-3)(8+(-10))=(-3)(8-10)=(-3)(-2)=+6.

Factor out the coefficient 1/2d+6
Ratling [72]
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:

1/2d + 6 = 1/2 (d + 3)

Hope this helps!

Write an indirect proof showing that the diagonals of a parallelogram intersect each other
____ [38]
Its an indirect proof, so 3 steps :-
1) you start with the opposite of wat u need to prove 
2) arrive at a contradiction
3) concludeReport · 29/6/2015261
since you wanto prove 'diagonals of a parallelogram bisect each other', you start wid the opposite of above statement, like below :- step1 : Since we want to prove 'diagonals of a parallelogram bisect each other', lets start by assuming the opposite, that the diagonals of parallelogram dont bisect each other.Report · 29/6/2015261


Since, we assumed that the diagonals dont bisect each other, 
OC≠OA 
OD≠OBReport · 29/6/2015261
Since, OC≠OA, △OAD is not congruent to △OCBReport · 29/6/2015261

∠AOD≅∠BOC as they are vertical angles, 
∠OAD≅∠OCB they are alternate interior angles 
AD≅BC, by definition of parallelogram 
so, by AAS, △OAD is congruent to △OCBReport · 29/6/2015261
But, thats a contradiction as we have previously established that those triangles are congruentReport · 29/6/2015261
step3 :
since we arrived at a contradiction, our assumption is wrong. so, the opposite of our assumption must be correct. so diagonals of parallelogram bisect each other.
