Answer:
2(x-5)(x+9)
Step-by-step explanation:
1) divide whole thing by 2 you get x^2+4x-45
2) from there you can factor it out to (x-5)(x+9)
3) Add the 2 back in on the front
Answer: use symolab
Step-by-step explanation:
Answer:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2
Step-by-step explanation:
The equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, r is the radius.
(h,k) is the coordinates for the center point.
In this image, it appears K is 3 units away from any point on the circle, making 3 the radius.
Our equation is now ( x - h )^2 + ( y - k )^2 = 3^2
Now, we need to find the coordinate of K; the center point.
K's x is -1 and K's y is also -1.
Our equation is now:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2
Answer:
m<11=5.75
Step-by-step explanation:
<u>since you already know what m<4 is </u>
<u>we just have to divide the result (63) by 4</u>
<u>63%4=15.75 </u>
therefore m<1= 15.75
Answer:
95
Step-by-step explanation:
Use the mean formula: mean = sum of elements / number of elements
Plug in the mean and number of elements, then solve for the sum of the numbers:
mean = sum of elements / number of elements
19 = sum of elements / 5
95 = sum of elements
So, the sum of the numbers is 95.
