what is the coefficient of the simplified expression of -5n+3(6+7n)

\(\begin{array}{rcll} -5n+3(6+7n) &=& -5\cdot n+3\cdot 6 + 3\cdot 7 \cdot n \\ &=& -5\cdot n+18 + 21 \cdot n \\ &=& 21 \cdot n -5\cdot n+18 \\ &=& 16 \cdot n +18\\ &=& 18 + 16 \cdot n\\ \end{array}\)

50 bacteria land on your tooth and they quadruple in number every hour, what is the equation?

\(\begin{array}{|l|lcl|} \hline \text{now} & 50 \ \text{ bacteria} &=& 50 \cdot 4^0 \ \text{ bacteria}\\ \text{after } 1 \text{ hour} & 50\cdot 4 \ \text{ bacteria} &=& 50 \cdot 4^1 \ \text{ bacteria}\\ \text{after } 2 \text{ hours} & (50\cdot 4^1)\cdot 4 \ \text{ bacteria} &=& 50 \cdot 4^2 \ \text{ bacteria}\\ \text{after } 3 \text{ hours} & (50\cdot 4^2)\cdot 4 \ \text{ bacteria} &=& 50 \cdot 4^3 \ \text{ bacteria}\\ \text{after } 4 \text{ hours} & (50\cdot 4^3)\cdot 4 \ \text{ bacteria} &=& 50 \cdot 4^4 \ \text{ bacteria}\\ \text{after } 5 \text{ hours} & (50\cdot 4^4)\cdot 4 \ \text{ bacteria} &=& 50 \cdot 4^5 \ \text{ bacteria}\\ \cdots & \cdots&&\cdots\\ \text{after } n \text{ hours} & &=& 50 \cdot 4^n \ \text{ bacteria}\\ \hline \end{array}\)

There is a 4-digit number such as: abcd. When you raise each number to the power of itself and add up their products, thus: a^a + b^b + c^c + d^d, you get the original number that you started with, namely: abcd!. What is this unique 4-digit number? Thanks and have a good day.

\(\begin{array}{rcll} a^a + b^b + c^c + d^d &=& abcd \\ 3^3+4^4+3^3+5^5 &=& 3435 \end{array}\)

.44 * 325  =  143

-40  and 7

-40 * 7   = -280

-40 + 7  = -33

1400cm = 14m

So we have

14  = 33θ

θ = 14/33 rads

Vampires are fake

2^5 is 32 because

2x2x2x2x2= 32

Hawkeye

"Is"  means " = "

"Of " means "multiply"

"What number"  = "N"     so we have

14 = .35N    divide both sides by .35

40  = N     ....  and that's the number

Nope i havent

No, I am just really sure I like 5th wave more! I thought you've watched it.
