The side lengths of a triangle are given by the expressions 5x + 3, 5x + 5, and 3x – 2. write and simplify a linear expression for the perimeter of the triangle.

13 x + 6

Step-by-step explanation:

Perimeter of triangle  =  All the sides added together

( 5 x + 3 ) + ( 5 x + 5 ) + ( 3 x - 2 ) = 13 x + 6

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

answer: your answer is c
