Atriangle has a perimeter of 58 feet. if the three sides of the triangle are n, 3n+4, and 4n-10, what is the length of each side?

  side lengths are 8, 28, and 22 feet

Step-by-step explanation:

The perimeter is the sum of the lengths of the three sides:

  58 = n + (3n+4) + (4n-10)

  64 = 8n . . . . . collect terms, add 6

  8 = n . . . . . . . .divide by 8. First side length

  3n+4 = 3·8 +4 = 28 . . . . second side length

  4n-10 = 4·8 -10 = 22 . . . . third side length

The side lengths are 8 ft, 28 ft, 22 ft.

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!
