The answer is 7xy - 14x

Explanation:
To distribute, you take the number that is outside of the parenthesis and you multiply it each by the numbers in the parenthesis. So 7x times y = 7xy, and 7x times -2 = -14x

7xy-8x because you distribute the x even if there is another variable inside the parentheses

Klio2033 [76]

Answer:

  • k = 0.032
  • P0 = 131.836

Step-by-step explanation:

Perhaps you want to use the points (t, P) = (4, 150) and (6, 160) to find the parameters P0 and k in the equation ...

  P(t)=P_0\cdot e^{kt}

We know from the given points that we can write the equation as ...

  P(t)=150\left(\dfrac{160}{150}\right)^{(t-4)/(6-4)}=150\left(\dfrac{16}{15}\right)^{\frac{t}{2}-2}\\\\=150\left(\dfrac{16}{15}\right)^{-2}\times\left(\left(\dfrac{16}{15}\right)^{\frac{1}{2}}\right)^t

Comparing this to the desired form, we see that ...

  P_0=150\left(\dfrac{16}{15}\right)^{-2}\approx 131.836\\\\e^{k}=\left(\dfrac{16}{15}\right)^{1/2}\rightarrow k=\dfrac{1}{2}(\ln{16}-\ln{15})\approx 0.0322693

So, the approximate equation for P is ...

  P(t)=131.836\cdote^{0.032t}

And the parameters of interest are ...

  • k = 0.032
  • P0 = 131.836

A piece of land is to be fenced and subdivided as shown to that each rectangle has the same dimensions. Express the total amount
nlexa [21]
There are 3 rectangles.

In the plane, each rectangle has 2x + 7 horizontal side.

The fence covers 3 horizontal sides => 3 (2x + 7)

In the plane, the vertical sideis x. And the fence covers 4 vertical sides => 4x

Then the total amount of fecncin is: 3(2x+7) + 4x = 6x + 21 + 4x = 10x + 21

Answer: 10x + 21<span> </span>
