You have a rectangular yard that measures 16 feet Long by 14 feet wide.it id covered in grass except For in the Center,where there is a circular fountain With a diámeter of 4 feet.what is the área of the grass porción of your yard ? Round your answer to the nearest hundredth . A.131.43. B.173.74ft2. C.211.43 ft.2. D.263.74 ft.2 please help me
Answers
A of the fountain= πR²
d=2R
4=2R
R=4:2=2
A of the fountain= 2²π=4 *3,14= 12,56 feet²
A of the grass portion= 224-12,56= 211,43 feet²
answer d)211,43 feet²

Answers
Answer:
The required expression is
Step-by-step explanation:
The difference of squares formula is given by
We have been given that one factor is 2x+5. Hence, a = 2x, b = 5
It means that other factor must be (a-b) = (2x-5)
Hence, in order to find the expression, we can multiply the factors.
Using the difference of squares formula
Therefore, the required expression is
A. 10a^4b^3
B. 3a^4b^4
C. 10a^4b^4
D. 3a^4b^3
Answers
15a^9b^4 / 5a^5b = 3a^(9-5)b^(4-1) = 3a^4b^3
The correct result would be D. 3a^4b^3.

Step-by-step explanation:
19.65 + 2.35 is exactly 22, not including tax
Answer:
A and C
Step-by-step explanation:
A. 15% off $25
15% = 0.15
0.15 x 25 = 3.75
25 - 3.75 = 21.25
22 or under? Yes
B. 30% off $32
30% = 0.30
0.30 x 32 = 9.60
32 - 9.60 = 22.40
22 or under? No
C. $19.65 plus a 2.35 shipping fee
19.65 + 2.35 = 22
22 or under? Yes
D. $20.45 plus a $1.60 shipping fee
20.45 + 1.60 = 22.05
22 or under? No
Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!

The all other 3 factors of the equation x⁴ + 2x³ − 7x² − 8x + 12 will b e(x + 2),(x - 1) and (x + 3).
What are the roots of an equation?
Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
Given the equation,
x⁴ + 2x³ − 7x² − 8x + 12
If (x - 2) is a factor of the equation then it should be divisible by it.
So,
(x⁴ + 2x³ − 7x² − 8x + 12) / (x - 2) = (x³ + 4x² + x - 6)
Now divide by (x - 1) of (x³ + 4x² + x - 6)
(x³ + 4x² + x - 6) / (x - 1) = x² + 5x + 6
So,
⇒ (x - 2)(x - 1)(x² + 5x + 6)
⇒ (x - 2)(x - 1)( x² + 2x + 3x + 6)
⇒ (x - 2)(x - 1)[ x(x + 2) + 3(x + 2) ]
⇒ (x - 2)(x - 1)(x + 2)(x + 3)
Hence "The all other 3 factors of the equation x⁴ + 2x³ − 7x² − 8x + 12 will b e(x + 2),(x - 1) and (x + 3)".
