Answer:
Step-by-step explanation:
x^2-10x+21
(x-7)(x-3)
find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10
Answer:
C
Step-by-step explanation:
Since the circle is inscribed inside of the square, its diameter is the same as the side length of the square, or 8. This means that the radius is 8/2=4. The formula for the volume of a circle is 
, or in this case 
. The area of the square is 8*8=64 square feet. 50.24/64 is equal to 78.5%, or answer choice C. Hope this helps!
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
The equation of the blue line in the given graph is y = -x/2 + 2 .
In the question ,
a line graph is given,
we have to find the equation of the blue line .
to find the equation of line , we need at least two points ,
So , from the graph we can see that the two points from where the blue line passes the graph are (4,0) and (0,2) .
the slope = (2-0)/(0-4)
m = 2/(-4)
m = -1/2
So , the equation of the line passing from the points (4,0) with slope -1/2 , is
(y - y₁) = m(x - x₁)
y - 0 = (-1/2)(x - 4)
y = -x/2 + 2
Therefore , The equation of the blue line in the given graph is y = -x/2 + 2 .

Answer:
the answer would be 4/10 but the simplified version would be 2/5.
Step-by-step explanation:
add up how many bows you have, that will be the denominator. Then, the numerator is the number of purple bows. and if your going to simplify it divide the numerator and denominator by 2.
