this is a thing were you match them sooo yeah lol
the cost of the laminate flooring per square foot

the area of the kitchen

the labor fee

the cost of the laminate flooring for the entire room

see the procedure

Step-by-step explanation:

we have

This is a linear equation in slope intercept form

where

The slope m is equal to

The slope represent the cost of the laminate flooring per square foot

The y-intercept is equal to

The y-intercept represent the labor fee

The term (st) represent the area of the room (s and t are the dimensions of the rectangular kitchen)

The cost of the laminate flooring for the entire room is 10.11(st)

step-by-step explanation:

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
