Answer:

x³ -x²-30x+72

Step-by-step explanation:

→ ( x - 3 ) ( x - 4 ) ( x + 6 )

[ expand and open brackets ]

→ ( x² -4x -3x + 12 ) ( x + 6 )

[ simplify ]

→ ( x² -7x + 12 ) ( x + 6 )

[ expand ]

→ x³ +6x² -7x²  - 42x + 12x + 72

[ simplify/ final answer ]

→ x³ -x² -30x +72

Brainliestis there is steps What is the solution to the equation log⁡〖 (2x+4)〗=2 ? Round to the nearest hundredth, if necessary.
Minchanka [31]

Answer:

x = 48

Step-by-step explanation:

log⁡〖 (2x+4)〗=2

Raise each side to the base of 10

10 ^log⁡〖 (2x+4)〗=10^2

The 10 ^log cancels

2x+4 = 100

Subtract 4 from each side

2x+4-4 = 100-4

2x = 96

Divide by 2

2x/2 = 96/2

x =48

maks197457 [2]

Answer:

$7,305.50

Step-by-step explanation:

The computation of the FICA tax pay in 2005 is shown below:

Medicare = 1.45% × $119,000 = $1,722.50

And, Social security tax = 6.2% × 90,000  = $5,580

So, the FICA tax in 2005 is

= Medicare tax + Social security tax

= $1,722.50 + $5,580

= $7,305.50

How long would it take you to double your money is the bank pays 3.6% interest, compounded
Lapatulllka [165]

Answer:

t=19.25\ years

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=?\ years\\P=x\\r=3.6\%=3.6/100=0.036\\A=2x  

substitute in the formula above

2x=x(e)^{0.036t}  

solve for t

simplify

2=(e)^{0.036t}  

Apply ln both sides

ln(2)=ln[(e)^{0.036t}]

Applying property of exponents

ln(2)=[0.036t]ln(e)

Remember that ln(e) =1

ln(2)=[0.036t]

t=ln(2)/[0.036]

t=19.25\ years
