Answer:
3985
Step-by-step explanation:
Note: predecessor means a number before for example predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.
The predecessor of the predecessor of 2987 = 2987-2 = 2985
Let 2985 be x
The greatest 3 digit number = 999
And the successor of the greatest 3 digits number would be = 999+1 = 1000
let 1000 be y
We have find the sum of x and y
= 2985+1000
= 3985
Answer:

Step-by-step explanation:
This is the answer because 147 ÷ 100 = 1.47
The surface area of the cube is 64 cm².
<h3 /><h3>What is volume?</h3>
Volume is the amount of space that is enclosed within a container.
To calculate the surface area of the cube, we use the relation below.
Formula:
- A = 6V
............ Equation 1
Where:
- A = Surface area of the cube
- V = Volume of the cube.
From the question,
Given:
Substitute this value into equation 1
- A = 6(35)

- A = 6(10.6999)
- A = 64.2
- A = 64 cm²
Hence, The surface area of the cube is 64 cm².

Possibly A)249.6
Explanation
It is 4:2
Since it is similar AB is double the size of AB' and BC is double the size of BC'. so 4:2 4 is double the size of 2.
