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:
The amount of intrest gained was B. $7.50
Step-by-step explanation:
Mark invested $125.
He gaines 3% per year and he did it for 2 years.
.03 x 2 =.06
125 x .06 = 7.50
B. $7.50
Hope this helps!

The answer would be x = 4 miles.
Answer:
-8c+6
Step-by-step explanation:
2(-6c+3)+4c = -12c+6+4c = -8c+6
Answer: its 180
Step-by-step explanation: length times width is the area. 15 times 12 is 180
