1 answer:
Answer:
729 is a perfect cube. The number whose cube is 729 is 9.
Explanation:
Let us find the cubes of natural numbers from starting
1 x 1 x 1 = 1
2 x 2 x 2 = 8
3 x 3 x 3 = 27
4 x 4 x 4 = 64
5 x 5 x 5 = 125
6 x 6 x 6 = 216
7 x 7 x 7 = 343
8 x 8 x 8 = 512
9 x 9 x 9 = 729
10 x 10 x 10 = 1000
So we got that 729 is the cube of 9, so 729 is a perfect cube.
The number whose cube is 729 is 9.

5(x-3)+7=-45
Step-by-step explanation:
The only possibly way for 5 to multiply 2 numbers is if those numbers are in parenthesis
14/19 if you add the amount of nickels and dimes together and then for the denominator just add all of the coins together.
4 x (3+4) because 4x3=12 and 4x4=16
16+12=28 in which 4x7=28 since 3+4 is 7
So 4 x (3+4) would be the correct answer
