Answer:
an acute triangle
Step-by-step explanation:
an acute triangle has angles that are less than 90 degrees
right triangles have a right angle
obtuse triangles have angles greater than 90 degrees
We can solve this using the FOIL method.
= (7x + 3)(7x - 3)
= (7x * 7x) + (7x * -3) + (3 * 7x) + (3 * -3)
= 49x - 21x + 21x - 9
= 49x - 9
