8 0

Answer:

x² + 2x - 15 = 0

x² + 2x + 1 = 16

(x + 1)² = 16

You can then go forward with that to solve it:

x + 1 = √16

x = -1 ± √16

x = -1 ± 4

x = 3, -5

The longest side of a triangle is 8 more units than the shortest side. The third side is 4 times the length of the shortest side

iogann1982 [59]

Answer:

10 3/4, 4 3/4, and 9 1/2

Step-by-step explanation:

We're going to let x represent the length of the longest side. The perimeter is

x +(x-6) +2(x-6) = 25

4x -18 = 25

4x = 43

x = 43/4 = 10 3/4

Then x-6 = 4 3/4.

Multiply that two to get 8 3/2 = 9 1/2

I hope this helped! :)

Andreyy89

Step-by-step explanation:

Both of them had $x

Later

Jensen=x-64

Raju=x-148

Jensen=3*Raju

x-64=3x-444

3x-x=444-64

2x=380

x=$190
