Solve 8x − 2(x + 1) = 7x + 8. (5 points) 6 −6 −10 10

8x − 2(x + 1) = 7x + 8

8x-2x -2=7x+8

6x-2=7x+8

6x-7x-2=8

-x=8+2

-x= 10

X=10/-1

X= -10

answer: 193

explanation:

200-7 = 193

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
