Answer:

20-(4(3)+7)=20     or      20-C=G

Step-by-step

The money allowed is $20 so the cost of everything subtracted from 20 is equal to the amount of change received a.k.a G

Complete the following: (2x +3y)^2 = (2x)^2+2(2x)(3y) +(____)^2
FrozenT [24]

Answer:

Complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

Step-by-step explanation:

We have given equation (2x+3y)^2=(2x)^2+2\times (2x)\times (3y)+..........^2

We have to find the function in place of blank space and complete the function

We know the algebraic equation (a+b)^2=a^2+b^2+2ab

So (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

So in place of blank pace there will be (3y)^2

And complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

Can someone fr help me with this like right now i’ll appreciate it sm
rjkz [21]

Step-by-step explanation:

Since

\frac{108}{72}  =  \frac{3}{2}

\frac{72}{48}  =  \frac{3}{2}

\frac{48}{32}  =  \frac{3}{2}

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

y = a(b) {}^{x}

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

y =  32 ( \frac{3}{2} ) {}^{x}

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.

2013- 162

2014- 243
