Answer:
3b^7a^6c^9/64
Step-by-step explanation:
Answer:
The correct answer is last option 78.5%
Step-by-step explanation:
Points to remember
Area of circle = πr²
Where r is the radius of circle
Area of square = a²
Where 'a' is the side length of square
<u>To find the area of circle</u>
Here r = 10 cinches
Area = πr²
= 3.14 * 10²
= 3.14 * 100 = 314
<u>To find the area of square</u>
Here a = 20 inches
Area = a²
= 20²
= 400
<u>To find the probability percentage</u>
Probability = area of circle/Area of square
= (314/400)*100
78.5 %
8 * 24 feet = 192 sq feet per 5 hours
12* 36 = 432 square feet
432 is 2.25 times the area of 192 square feet
So, it takes 5 * 2.25 = 11.25 hours
Answer:
The answer is c
Step-by-step explanation:
(7,9) (3,25)
<u> Equation:</u>
x(x - 5) + 3(x + 5)
<u>Steps:</u>
x(x - 5) + 3(x + 5)
<u>Expand:</u>
x(x - 5 ): x^2 - 5x
x^2 - 5x + 3(x + 5)
<u>Expand:</u>
3(x + 5): 3x + 15
x^2 - 5x + 3x + 15
<u>Add Similar Elements: </u>
-5x + 3x
= -2x
Answer x^2 - 2x + 15 Doesn't Factor
Hope that helps!!! : )
