Answer:
100C4
Step-by-step explanation:
Choosing 96 thing from a 100 would have the same number of possibilities as choosing 4 things from 100.
100C96 = 3,921,225
and
100C4 = 3,921,225
*Notice 94+4 = 100
To generalize the situation,
xCy = xC(x-y)
Here we'd have
100C96 = 100C(100-96)
or
100C96 = 100C4
DEG is an quadrilateral triangle so they have the same length on all 3 sides.

Answer: 4xy(y² + 2x)
Step-by-step explanation:
When we have brackets like this, we multiply whatever is left of the brackets by everything inside.
1) 4xy multiplied by y²
4xy x y² = 4xy³
2) 4xy multiplied by 2x
4xy x 2x = 8x²y
3) Add together 4xy³ and 8x²y
4xy³ + 8x²y
1)
(x-3)(x-1)
2)
(x+3)(x-1)
3)
(x+4)(x+2)
4)
(x+5)(x-3)
5)
(2x+4)(x-4)
6)
3x(x+2)
7)
(x+4)(x-4)
8)
(2x+4)(2x+8)
9)
(2x+1)(x-3)
10)
have to use quadratic
11)
(x-10)(x-2)
12)
(3x-4)(2x+1)
Answer:
-5
Step-by-step explanation:
y=-2/3-5x
Rewriting the equation in the form y = mx+b where m is the slope and b is the y intercept
y = -5x -2/3
The slope is -5 and the y intercept is -2/3
