Answer:
8. Obtuse
11. Obtuse
Step-by-step explanation:
c^2 = a^2 + b^2
for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute
Answer:
4,0
Step-by-step explanation:
<span> x²+4x-1 - (3x - 7) = x² + 4x - 1 - 3x +7 = x² + x + 6
</span>x² + x + 6 should be added to 3x - 7 to make x²+4x-1.
