Answer:
18
Step-by-step explanation:
Honestly you can just use a calculator for this.
But if you want to know how to actually do it, multiplying something by a fraction is just dividing it by its reciprocal (just flipping the numerator and the denominator).
Therefore...
72/4 is 18, 72 x 1/4 = 18
You can see that the base is 5 units.
The height is 3.
The area of a parallelogram is
A = B * H
A = 5 * 3
A = 15 units^2
Hope this helps!
The first two graphs are D) and D).
For the last one (above), the triangles are not congruent (D), because C --> C' doesn't follow the same translation rule as A, B --> A', B'
I did the math and I think that it's 3.7
That would be the SSS postulate.
