Answer: x^2+8x+15
Step-by-step explanation:
(x+5)(x+3)
x^2+3x+5x+15
x^2+8x+15
Answer:
81π
Step-by-step explanation:
Area of a circle formula is : 
. r stands for radius.
Radius is half of the diameter. To solve for the area of the circle, we must replace r with diameter/2 which is 9 (18/2 = 9).
Now, the question wants us to give the answer in terms of pi. So we are going to simplify the equation WITH PI. Meaning, we aren't going to multiply pi. So we will just simplify 9 squared to 81.
So in terms of pi the area is 81π
Answer:
Either way you can in 144 ways.
Step-by-step explanation:
According to the statement we have 3 flowering shrubs and 3 flowerless shrubs.
We name them as follows:
S = flowering shrub
N = non flowering shrub
Now the only pattern in which these bushes can be arranged alternately as follows:
N-S-N-S-N-S-N
Therefore, to calculate the number of forms it would be:
Number of shapes: 4 * 3 * 3 * 2 * 2 * 1 * 1 = 144
Which means there are 144 ways.
Now if we organize them in a circle in the same way
again it would be the same number of ways to organize them: 144 ways.
This is because the nun's last blooming shrub is left outside.
Answer:
n + 5
Step-by-step explanation:
if last year melly was N year old, she is now n+1 years old.
So, in four years, she will be
(n + 1) + 4 years old
meaning that she will be n + 5 years old.
hope this helps!! :)
The fraction for this would be 42
The percentage will be 42.85714285%
