The perimeter of a triangle is 34 feet. One side of the triangle is 2 times the second side. The third side is 6 feet longer than the second side. Find the length of each side.

Step-by-step explanation:

Let 1st side of triangle be x

so,

length of given side will be x, 2x, 6+x

we know that,

perimeter of triangle = 34

x+2x+(6+x)= 34

4x+6= 34

4x = 34-6

x= 28÷4

:x= 7

2x = 7*2= 14 ft

6+x = 6+7 = 13 ft

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
