Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
Hope it helps!
Answer:
(p∘q)(5) = 2
(q∘p)(5) = -1
Step-by-step explanation:
The composition of functions can be written a little differently, perhaps making it easier to understand.
(p∘q)(x) = p(q(x))
(p∘q)(5) = p(q(5)) = p(2·5 -5) = p(5) = 5 -3
(p∘q)(5) = 2
__
(q∘p)(5) = q(p(5)) = q(2) = 2·2 -5
(q∘p)(5) = -1

--- Distributive property
Step-by-step explanation:
Given
Ferns = 4
Palms = 2
Lillies = 10
Shrubs = 8
Required
Show the total cost of plants as an expression
Shorten it using the distributive property
First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;
So, 4 Ferns = 4F
2 Palms = 2P
10 Lilies = 10L
8 Shrubs = 8S
Total Plants = Summation of the above parameters

The above expression represents the total plants bought;
Now, to apply the distributive property; we simply look for a common factor;
In this case, the common factor is 2;
So,
becomes
