The answer to this question is p+3
Answer:
Step-by-step explanation:
For problem 10:
1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)
2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)
3. 9/x=(9+6)/10 (Substitute the given values into this equation)
4. x=6 (Use algebra to solve for x)
For problem 11:
1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)
2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)
3. 14/(14+7)=18/(18+x) (Substitute given values)
4. x=9 (Solve for x)

Answer:
I believe the answer is D?
Step-by-step explanation:
The correct value of the length of each square tile is 3½ feet long.
Answer:
Total area of mosaic = 600.25 sq.ft
Step-by-step explanation:
We are told the length of each square tile = 3½ ft.
Area of square = L²
Where L is length of side.
Thus;
Area = 3½ × 3½
Area = 49/4 sq.ft
Now, an array of 7 x 7 means 7 rows and 7 columns
Thus, total number of square tiles = 7 x 7 = 49 tiles
So,
total area of whole mosaic = number of tiles × Area of 1 tile
Total area = 49 × 49/4 = 600.25 sq.ft
