Answer:
Multiplication with 2.
Step-by-step explanation:
In this question, we have to find the operation which is equivalent to adding a number to itself.
The operation is multiplication with 2.
If a number is multiplied with 2, then the operation is equivalent to adding a number to itself.
For example, if you multiply the number x with 2, the result is 2x and again if you add x with x, you will get the same result as 2x. (Answer)
Answer:
V = 15.75w² + 10.5w
Step-by-step explanation:
A rectangular prism is the same as a cuboid and the volume of a cuboid is length multiplied by width multiplied by the height.
And we were provided with the following:
Length = 5.25cm
Width is unknown,= w
The height is said to be 2cm longer than 3 times it's width.
The above statement can be mathematically represented as ;
H = 3w + 2
Apply the above into the formula given and we have
5.25 × w × (3w + 2)
Expand the above and we have
V = 5.25w × (3w + 2)
V = 15.75w² + 10.5w
The change in Emily's saving balance is negative $55 or x - $55.
Answer:
It happened in 168 minutes
Step-by-step explanation:
24: 48, 72, 96, 120, 144, 168
14: 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168
The common LCM is 168. It happened in seven 24's and in twelve 14's
