Answer:
C. 1 - 2x > 13
Step-by-step explanation:
you just substitute
Answer:
40
Step-by-step explanation:
because 40 goes in to 8 5 times and it also goes into 80 2 times
The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product
Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: 
10^2 = 100
Then you do
or 3.14 times 10 = 314.1592654 or just 314.

The required proof of parallelogram is given below,
What is parallelogram?
A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry. The opposing or confronting sides and the opposing angles in a parallelogram are of equal length.
For a parallelogram, opposite sides are always equal and parallel.
So for the given parallelogram, we get AD = BC and AD and BC are parallel.
AD and BC is parallel and DC is common side, therefore,
......(1)
Given
.......(2)
Therefore, from condition (1) and (2), we get

If
then DC bisects the angle
