The perimeter of a rectangle is dependent on the length of each of its sides. Suppose the base of a rectangle is two more than i

Bezzdna [24]

Perimeter=4h+4

If the base is 2 more than the height, it gives us the equation:
b=h+2

The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.

This can be simplified to be 2h+4+2h or 4h+4

Answer:

It takes 26 2/3 gallons to make a 400 mile trip.

Step-by-step explanation:

This question is simply asking for the number of miles per gallon . In math, <em>per</em> means this is meant to be written as a fraction.

"If a trip of 270 miles required 18 gallons of gas" is actually saying "270 miles per 18 gallons." This can be written as a fraction like so: 270/18.

If we're looking for the amount of gas used for a 400 mile trip, we have the fraction: 400/g, g being the amount of gallons it took to make that trip.

Now we can set up the proportion: $\frac{270}{18} =\frac{400}{g}$

Cross multiply and solve accordingly.

$\frac{270}{18} =\frac{400}{g}$

400 $270g = 400 *18\\ 270g = 7200\\g=26\frac{2}{3}$ /g

So the answer is:

It takes 26 2/3 gallons to make a 400 mile trip.
