Answer:
n=−5
Step-by-step explanation:
n−4−3n=3n+6−3n
−2n−4=6
Step 2: Add 4 to both sides.
−2n−4+4=6+4
−2n=10
Step 3: Divide both sides by -2.
−2n
/−2
= 10
/−2
n=−5
a corner of a cube connects 3 sides to each other,
then add the side of the cut
so it would have 4 sides
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
