Answer:

It's definitely D.

Step-by-step explanation:

It's D because it has a -2m and -8m if you add them you get the -10m in the equation the m2 is already there And if you multiply -2 * -8 you'll get 16 positive, because a negative plus a negative is a positive.

Answer:

D.

Step-by-step explanation:

The last table is the correct choice. Because when you use the X method on the equation your answers from that is (m-8)(m-2).

Answer:

<h2>The circumference is multipled by 4.</h2>

Step-by-step explanation:

The formula of an area of a circle"

A=\pi r^2

The formula of a circumference of a circle:

C=2\pi r

The area multipled by 16:

16A=16\pi r^2\\\\16A=\pi(4^2r^2)\\\\16A=\pi(4r)^2

The radius has increased fourfold, therefore:

C'=2\pi(4r)=4(2\pi r)=4C

The circumference is multipled by 4.

You can calculate the area and check the circumference:

r=11.6\ in\\\\A=\pi(11.6)^2=132.56\pi\\\\16A=(16)(134.56\pi)=2152.96\pi\ in^2

Calculate the radius:

\pi r^2=2152.96\pi             <em>divide both sides by π</em>

r^2=2152.96\to r=\sqrt{2152.96}\\\\r=46.4\ in

Calculate the circumference of both circles:

r=11.6\ in\\\\C=2\pi(11.6)=23.2\pi\ in

r=46.4\ in\\\\C'=2\pi(46.4)=92.8\pi\ in

\dfrac{C'}{C}=\dfrac{92.8\pi}{23.2\pi}=4\to C'=4C

Marisa bought four bottles of water.Each bottle of water was 95 cents. Write an equation with the same product as the total cost
meriva

Answer:

5\times 0.76= 3.8

Step-by-step explanation:

Given: Marisa bought four bottles

          Price of each bottle is $0.95.

Solving with the factors as given to find the total cost paid by Marisa.

Total cost= 4\ bottles\times \$ 0.95= \$ 3.8

∴ Total cost paid by Marisa is $3.8.

As given to write an equation with the same product as the total cost but different factors.

∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"

We already find the total cost she paid is $3.8.

Now, writing an equation with different factors, as total cost remain same.

5\times x= 3.8

Dividing both side by 5

we get x= $ 0.76

∴ The required equation is 5\times 0.76= 3.8
