Randy is checking to determine if the expressions 2 x + 2 + 4 x and 2 (3 x + 1) are equivalent. When x = 3, he correctly finds that both expressions have a value of 20. When x = 2, he correctly evaluates the first expression to find that 2 x + 2 + 4 x = 14. What is the value of the second expression when x = 2, and are the two expressions equivalent?
The value of the second expression is 7, so the expressions are not equivalent.
The value of the second expression is 12, so the expressions are not equivalent.
The value of the second expression is 14, so the expressions are equivalent.
The value of the second expression is 20, so the expressions are equivalent.

8 2/3 is the answer

step-by-step explanation: just use a calculator

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

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
