The prime factorization of 343 is 7^3. So the cube root of 343 (7^3) is just 7.
Irrational: Cannot be expressed in the form of a/b. 7/1 = 7 No
Rational: Can be expressed in the form of a/b. 7/1 = 7 Yes
Integer: Set of all negative and positive numbers (not a fraction). 7 is a positive number. Yes
Whole: Set of numbers ranging from 0 to infinity (not a fraction). 7 is a positive whole number. Yes
Natural: Set of all positive numbers from 1 to infinity (not a fraction). 7 is positive. Yes
I don’t understand your questions because it’s all connected together. Could you maybe separate the actual question in the comments for me to help?
5*2 = 10
3^2 = 3*3 = 9
10 + 9 = 19
Answer: 19
Answer:
Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3.
Step-by-step explanation:
The rectangle ABCD is dilated by a factor of 3 to get the rectangle WXYZ whose area is found to be 72 cm².
Let the dimensions of the dilated rectangle WXYZ are a cm by b cm.
So, ab = 72 ........... (1)
Now, the dimensions of the original rectangle are 3 times lesser than the dimensions of rectangle WXYZ.
So, the area of rectangle ABCD will be
cm² {from equation (1)}
Therefore, Tristan is correct, because he needs to find the possible dimensions for rectangle WXYZ and then divide each dimension by 3. (Answer)
