Is it just me or is it just that I can't see anything
Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
hope that helped!
Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x
Answer:
-1/100

Answer:
27 cubic meters
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of cube = 54 square meters
Let, Side = a
Then, Area of cube = 6
54 = 6 
= 9
a = 3
So, we can calculate the volume of cube by using following formula
Volume of cube = 
By putting the value in the formula, we get
Volume of the cube = 
= 27 cubic meters
