Volume is l*w*h, but in a cube the sides are all the same, so it is l*l*l, or in this case x*x*x = x3■
15 h
s + 9
z - 7
n + 11
x-2
The expression is 9*x.
To write a variable expression for "W increased by 4," you simply take the variable ( W ) and add 4 to it. The expression would be written as ( W + 4 ). This indicates that you are taking the value of ( W ) and increasing it by 4 units.
40 + x
10n
10n
You can write 2X, where X is the length of the string.
5 = x
answer: 5n
15 h
2n/5 or (2/5)*n
(x + 9)
x-2
