Answer:
x=4
Step-by-step explanation:
Because 4 to the power of 2 is 16.
Then, you subtract: 16x - 7x
Then, what you are going to see is 9x=3x+24
So, you subtract: 9x - 3x
Finally, you will have 6x=24... You divide: 24/6 and the answer is x=4.
Answer:
According to the question 25% of the students wore jackets.
Thus 25% of 12 wore jackets
The number of students can be found easily by multipling 12 with 25//100
12*25/100
12*1/4
12/4
thus, 3 students
Therefore, option 3 is correct
A ) P = 6 * 0.5 = 3 m ( correct )
B ) Apothem = 0.5 * √3 / 2 = 0.433 m = 43.3 cm ( correct )
C ) A = 6 * 0.5² √3 / 4 = 0.649519 m² ≠ 1.299 m² ( false )
D ) r = 0.5 m ( correct )
Answer: C ) is false
