(2x+3)(3x+4)

=(2x+3)(3x+4)

=(2x)(3x)+(2x)(4)+(3)(3x)+(3)(4)

=6x²+8x+9x+12

=6x²+17x+12

Therefore, the answer is 6x²+17x+12

First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!

Help me please. I really need help
artcher [175]

Answer:

B.  $42.60.

Step-by-step explanation:

On the first day  price is 43.85 + 2.70 = $46.55

second  day       price is 46.55 + 2.70 = $49.25

For the next 2 days  it goes down $1.10 so the price is  $49.25 - 2.20=$47.05

On the last day it loses $4.45 so the final  price is  $47.05-4.45 =  $42.60.

Find the function of which is the solution of 36y"-48y'-48y=0 with initial conditions y1(0)=1. y1'(0)=0
lilavasa [31]

Answer:

y=\frac{1}{4} e^{2x}+\frac{3}{4} e^{-\frac{2}{3}x }

Step-by-step explanation:

Let,  D=\frac{d}{dx}

Now, us simplify the given differential equation and write it in terms of D,

36y''-48y'-48y=0

or, 3y''-4y'-4y=0

or, (3D^2-4D-4)y=0

We have our auxiliary equation:

3D^2-4D-4=0

or, (3D+2)(D-2)=0

or, D=2, - \frac{2}{3}

Therefore our solution is,

y=Ae^{2x}+Be^{- \frac{2}{3}x}

and, y'=2Ae^{2x}-\frac{2}{3}Be^{\frac{2}{3}x }

Applying the boundary conditions, we get,

A+B=1

2A-\frac{2}{3}B=0

Solving them gives us,

A=\frac{1}{4} ,B=\frac{3}{4}

Hence,

y=\frac{1}{4} e^{2x}+\frac{3}{4} e^{-\frac{2}{3}x }

What do I need to do and what are the steps
Viktor [21]
So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5

change the 2/5 into decimals by 2 ÷ 5 = 0.4

multiply $55 with 0.4
55 x 0.4 = 22

so she ends up saving $22

A car dealership pays you 4% commission on your first $8,000 in car sales and 8% commission on additional sales over the $8,000.
Zigmanuir [339]

Answer:

Total Commission = $400


Step-by-step explanation:

Since total is $9000 (in sales) -- commision is 4% on the first $8000 and 8% in the additional part over $8000 (9000-8000=1000). So 8% on $1000.


<u>Total commission</u> = 4% of 8000 + 8% of 1000

= (0.04)(8000) + (0.08)(1000)

= 400


Total Commission is $400
