Answer:
Step-by-step explanation:
The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'
At first, let's take the unknown number as 'x' . (asked in the question).
So, the number we think about = x
Now, we need to multiply it by 3. So,
In the next part, we need to add 4 to it so,
Now, by squaring the result, we'll get the expression as,
<u>____________</u>

Answer:
Step-by-step explanation:
step 1
Find the surface area of the smaller rectangular prism
where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
step 2
Find the surface area of the cube
where
s is the length side of the cube
step 3
Find the lateral area of the cylinder
where
D is the diameter of the base
L is the length of cylinder
step 4
Find the area of the base of cylinder
we have
----> the radius is half the diameter
step 5
Find the surface are of the composite figure
we know that
The surface area of the composite figure is equal to the surface area of the smaller rectangular prism plus the lateral area of the cylinder, plus the surface area of the cube, minus the area of the two bases of cylinder
so
