Answer: 1. 3 • (x + 5) • (x - 5)
2. 2a*(2b+9)
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
2x + 9 - 17x - 15 - x =????
2x - 17x - x + 9 - 15 = 0
- 15x - x - 16 = 0
- 16x - 16 =0
-16x = 16
x = 16 / - 16
x = 1

Step-by-step explanation:
1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.
2. The area of a circle is πr² where r is the radius of the circle. It is true.
3. The area of a circle is equal to pi divided by the square of the radius. It is false.
4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.
5. If r = 2.1 m
Area of circle, A = πr²
= 3.14 (2.1)²
= 13.85 m²
Henc,e this is the required solution.
The dimensions would be 10 square units by 8 square units
