Answer:
The answer is C. 16
Step-by-step explanation:
Notepads of the same color = 4
As we have two sizes then total for the same color = 
Notepads of the different colors as we have to choose 3 different colors out of 4 = 4C3 = 4
For two sizes the total for the different color =
We can group these like - Same size same color package:
There are eight combinations
Size 1:
BBB
GGG
YYY
PPP
Size 2:
BBB
GGG
YYY
PPP
Next groups form like : Same size different color
Size 1:
BGY
BYP
GYP
BGP
Size 2:
BGY
BYP
GYP
BGP
So, we get total =
First, solve for the volume of the ball bearings by the equation,
V = πd³ / 6
Substituting the value of diameter given,
V = π(1 cm)³ / 6 = π/6 cm³ = 0.5236 cm³
Divide the amount of material given by this volume,
n = 5.24 cm³ / <span>0.5236 cm³ = 10
Therefore, there are 10 ball bearings that may be formed.</span>
Answer:
C. 8x - 16
D. 
+ 6x + 8
A. 2 (x + 3)
B. 7(2 - x)
C. -8x
D. 7x
Step-by-step explanation:
c.
To solve this problem, first, one must distribute, multiply every term inside the parenthesis by the term outside,
2(4x - 8)
=(2)(4x) + (2)(-8)
= 8x - 16
d.
To solve this problem, distribute, multiply every term inside one parenthesis by every term in the other, the combine like terms,
(x + 4)(x + 2)
= (x)(x) + (4)(x) + (2)(x) + (4)(2)
= + 4x + 2x + 8
= + 6x + 8
a.
Factor, write the given expression as the product of two expressions. Take out a common factor that both terms have,
2x + 6
= 2(x + 3)
b.
Factor this expression, take out a common factor, and rewrite the expression as the product of two other expressions,
14 - 7x
7(2 - x)
c.
Combine like terms,
2x - 10x
= -8x
d.
Combine like terms to solve this problem
3x + 4x
= 7x
