(256)-3/4
=256*-3/4
=-768/4
=-192
 
        
             
        
        
        
use FOIL (first, outside, inside last) 
4a * 3a = 12a² 
4a * -8 = -32a 
-6 * 3a = -18a 
-6 * -8 = 48 
-12a² - 32a - 18a + 48 
combine like-terms: -12a² -50a + 48
 
        
             
        
        
        
Answer: -3.125
Step-by-step explanation: -1 divided by 8 = .125
 
        
             
        
        
        
Answer:
y = 1/6 x^2 + 8/3 x + 49/6
Step-by-step explanation:
This is a parabola which opens upwards.
The distance of a point (x, y)  from the focus is
√[(x -  -8)^2  + (y - -1)^2] and
the distance of the point from the line y = -4 
= y - -4 
These distances are equal for a parabola so:
√[(x -  -8)^2  + (y - -1)^2] = y + 4
Squaring both sides:
(x + 8)^2 + (y + 1)^2  = (y + 4)^2
x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16
x^2 + 16x + 64 + 1 - 16 = 8y - 2y
6y = x^2 + 16x + 49
y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.

17 one point shots and 39 two point shots were made
Solution:
Given that,
At a basketball game, a team made 56 successful shots
They were a combination of 1- and 2-point shots
Let "x" be the number of 1 point shots
Then, 56 - x is the number of two point shots
The team scored 95 points in all
Therefore,
1(number of 1 point shots) + 2(number of two point shots) = 95
x + 2(56 - x) = 95
x + 112 - 2x = 95
x = 112 - 95
x = 17
Then, number of two point shots = 56 - x = 56 - 17 = 39
Thus 17 one point shots and 39 two point shots were made
