Answer:
4. 28 sq. inch
Step-by-step explanation:
First, Area of the square = l² = 2² = 4
Area of the triangle = 1/2 x b x h
= 1/2 x 2 x 6
= 6
Total surface area = Area of square + 4 x area of triangle
= 4 + 4 x 6
= 28
The value placed in the box that makes the system of equation with infinitely many solution is 12.
<h3>How to solve an infinitely many solution equation?</h3>
An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16. If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.
Hence,
y = -2x + 4
Therefore,
6x + 3y = 12
divide the equation(ii) by 3
2x + y = 4
y = -2x + 4
Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.

Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Polygon X is similar to polygon.
And Polygon X is three times the size of polygon Y.
So, it becomes,

Hence, perimeter of polygon Y is 27.
Therefore, Option 'C' is correct.
