Step-by-step explanation:
The surface area of an object will be all of it's side area's added up.
Looking at this, we can see that there are 4 sides with side lengths 2 and 5, and 2 with side lengths 2 and 2.
The area of a rectangle is it's length times width.
Since there are 4 of these sides:
.
Since there are two of these sides:
.

Answer:
The GCF (12, 78) is 6 and GCF (18, 176) is 2.
Step-by-step explanation:
Step 1:
The greatest common factor of the number is defined as the factor of two or more numbers. The acronym of Greatest common factor is GCF.
(a)
GCF (12, 78)
The greatest common factor of the two numbers 12 and 78 is calculated by Euclid’s algorithm as follows:
Therefore, the greatest common factor GCF is 6.
Step 2:
(b)
GCF (18, 176)
The greatest common factor of the two numbers 18 and 176 is calculated by Euclid’s algorithm as follows:
Therefore, the greatest common factor GCF is 2.
Consider the first blank is the green box.
Given:
The equations are
To find:
The value belongs in the green box
Solution:
We have,
...(i)
...(ii)
Adding (i) and (ii), we get
So, the value for the first black is 2x. It means the value belongs in the green box is 2x.
The values of three blanks are 2x, 0 and 13 respectively.
Therefore, the correct option is B.
