Answer:
The correct answer is 20x-1
The amount of balls in a given layer can be found by squaring the layer it is in
4 layers
top layer (1st) is 1
2nd is 4
3rd layer is 9
4th is 16
add them up
1+4+9+16=30
30 in that pyramid
This is the answer I got according to the app called “Math”
Answer:
For f(x) = 2x2 + 4x - 6, the answers that go in this ones box is, x-intercept: (1,0)
y-intercept: 0,–6)
For g(x) = -2x2 + 4x + 3, the answers that go in this ones box is, y-intercept
: (0,3)
For h(x) = 2x2 - 4x - 6, the answers that go in this ones box is, x-intercept: (3,0) y-intercept: 0,–6)
Step-by-step explanation:
Hope this helps :)
The midpoint is calculated by averaging the coordinates of its endpoints:

Now we can use the usual distance formula to get the length of SM:
