Answer:
A =63.585 in^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
A = pi (4.5)^2
A = pi(20.25)
We can approximate pi by 3.14
A = (3.14) (20.25)
A =63.585 in^2
For this case we have the following polynomials:

Adding the polynomials we have:

Rewriting we have:

Therefore, the result of the sum is:

Answer:
the sum of the polynomials is:

option 2
Answer:
19 out of 25
Step-by-step explanation:
Add 30+46= 76
Divide 76/100= 19/25
Answer:
Point P is the center of Rotation.
Answer:
(10a+5)²= 100 a( a+1) + 25
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given
(10a+5)²
By using (a+b)² = a² +2ab +b²
= (10a)²+ 2 × 10a× 5 + (5)²
= 100a² + 100a + 25
= 100 a( a+1) + 25
