Please please help me answer this question asap thank you

y = 800

x = 3

Step-by-step explanation:

3(y + 200) = 3000

distribute the 3 to everything in parentheses

3y + 600 = 3000

subtract 600 from both sides

3y = 2400

divide both sides by 3

y = 800

2(x + 5) = 16

distribute the 2 to everything in parentheses

2x + 10 = 16

subtract 10 from both sides

2x = 6

divide both sides by 2

x = 3

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.
