Answer:
The product of (x-3) and (x+7) is x² + 4x - 21
Step-by-step explanation:
The product of (x-3) and (x+7) is x² + 4x - 21
The product of (x - 3) and (x + 7) can be found as follows:
(x - 3)(x + 7)
open the bracket by multiplying
Therefore,
x(x) +x(7) - 3(x) - 3(7)
x² + 7x - 3x - 21
combine like terms
x² + 4x - 21
Out of the two parallelograms shown, we can say that A. Both I and II; congruent diagonals property.
<h3>Which of the shapes is a rectangle?</h3>
Rectangles can be proven to be rectangles by the congruent diagonals property.
This states that rectangles should be able to have diagonal lines extending from all sides within the rectangle that are perpendicular to each other.
These lines should bisect each other. As shown in the daigram, both shapes have that quality and so are both rectangles.

x + x+1 + x+2 =81
Simplify:
3x + 3 = 81
Subtract 3 from both sides
3x = 78
Divide both sides by 3
x = 26 or C). 26
