An isosceles trapezoid has a perimeter of 49 miles. its shorter base measures 12 miles and its longer base measures 23 miles. the two remaining sides have the same length; what is that length?

The perimeter is 49 miles, which means that all the sides added up must equal 49. Let's write and equation with the information given, where x is the magnitude of the two sides:

Simplify this a little bit to get x on one side:

Divide by 2 on both sides, and your answer is:

Therefore, the length of the two sides of the trapezoid are both 7 miles.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
