4(x-1)-3(x-2)=-8
How do you solve this?

-10

Step-by-step explanation:

x = -10

Step-by-step explanation:

Remember: PoE = Property of Equality.

Equation: 4(x - 1) - 3(x - 2) = -8

4x - 4 - 3x + 6 = -8 ^ Distributive PoE

1x + 2 = -8 ^ Combine like-terms

x = -10 ^ Subtraction PoE

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
