Question 1:
We can tell that this shape is a parallelogram because the diagonals bisect each other, which is a property unique to parallelograms.
Question 2:
72 + 72 = 144
This is not a right angle, so this shape cannot be a square or rectangle.
Since we have congruent base angles, each of those triangles are congruent isosceles triangles.
Thus, we have 4 sides of equal length. Thus, this shape must be a rhombus.
Question 3:
We know that AB and CD (the legs) are congruent since this is an isosceles trapezoid.
8y - 18 = 7y - 4
Subtract both sides by 7y
y - 18 = -4
Add both sides by 18
y = 14
That's your answer.
Have an awesome day! :)

Answer:
8x + 6 + 4 = 3x - (2x + 4)
Step-by-step explanation:
When Gio applies the distributive property, the equation above is the result. Naturally, I look at the 1st parenthesis I see and start the 1st distributive property there first. The 2nd distributive property would be the other parenthesis where you multiply by -1, so you would get 8x + 6 + 4 = 3x - 2x - 4
The answer is 8/27 just so you know
