Option D: 
is the solution
Explanation:
The given expression is 
We need to determine the factors of the expression by grouping.
The solution can be determined by factoring the common terms in the expression.
Let us group the expression.
Let us factor out the common terms from the two groups.
Thus, we have,
Thus, the factors of the expression is

Answer:
Area of Figure 1 = 48
Step-by-step explanation:
We are given CD and EF. We can use this to find the scale factor between the two shapes.
The scale factor from Figure 1 to Figure 2 is 7/4.
The scale factor from Figure 2 to Figure 1 is 4/7.
Perimeter of Figure 2: 16 × 7/4 = 28cm, which is correct.
Area of Figure 1: 147 × (4/7)^2 = 48cm^2 We square the SF as we only worked out the Length Scale Factor. The Area Scale Factor is the Length Scale Factor squared.

The height of the higher board above the water surface is 12 feet.
The distance from the high dive to the bottom of the deep end is 24 feet.
<h3>What does division mean?</h3>
Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.
<h3>What is the height of the higher board above the water surface?</h3>
In order to determine the height of the higher board, divide the height of the lower board by 25%.
Height of the higher board = 3 feet / 25%
3 / 0.25 = 12 feet
<h3>what is the distance from the high dive to the bottom of the deep end?</h3>
12 feet + 12 feet = 24 feet
