Answer:
x=4 and x= - 5
Step-by-step explanation:
In order to solve this we should re-arrange the equation:
This is equal to:
Then we can seperate this into:
So solving for x in both cases we get
If you put brackets around (2+1), your method of working is:
1) 15-4*(2+1)=3
2) 15-4*3=3
3) 15-12=3
You don't need any more brackets, as the BIDMAS (brackets, Indices, division, multiplication, addition, subtraction) rule does the rest of the job for you.
The answer is therefore: 15-4*(2+1)=3

Answer:
The length of each edge of the cube is 1 unit.
Step-by-step explanation:
Volume of the cube = x * x * x = x^3
So x^3 = 1
x = 1.
2d+3
2(8)+3
Multiply 2 and 8
16+3
19
So the answer is 19
