Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.

Answer: congruent central angles
Step-by-step explanation:
A central angle is an angle formed by two radii with the vertex at the center of the circle. In the diagram at the right, ∠AOB is a central angle with an intercepted minor arc from A to B. In a circle, or congruent circles, congruent central angles have congruent arcs.
These statements are true:
<span>1. The first number in an ordered pair is the x-coordinate.
2. The second number in an ordered pair is the y-coordinate.
3. The graph of a linear equation is usually a line.
</span><span>5. Ordered pairs are graphed as points in the coordinate plane.

1 yard=36".
25 yeards = 25*36" = 900"
3 rolls = 3*900 = 2700"
Each piece must be 22" long, so the number of pieces
= 2700/22 = 122 pieces (2684") with 16" left over.
