Can someone help me pls it’s freshmen work.

1) The equation has one solution.

2) A value of x that makes the equation true is 7, which when substituted into the equation and simplified makes the equation turn into 10 = 10.

3) A value of x that makes the equation false is 5, which when substituted into the equation and simplified makes the equation turn into 8 = 10.

Step-by-step explanation:

1) Since the equation is a simple problem, and answer question, it only has one solution.

2) The value of x is 7 because 3 + 7 equals 10, making said equation true. Similarly, you could perform 10 - 3, which makes you receive 7 in return. After this, you end up simplifying to 10 = 10, thus also making the equation true.

3) A value of x making the equation false can be many numbers, as long as they’re not 7. I chose 5, which would simplify into 8 (3 + 5 = 8), therefore making the equation false. To further prove this, we realize 8 = 10 makes the equation incorrect.

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.
