Drew has 4 pieces of rope 1 meter long each. he cuts each rope into fifths.
a. how many fifths will he have after cutting all the ropes?
b. how long will each of the fifths be in centimeters?

(a) Total number of fifth 20

(b)Length of each fifth will be 0 cm

Step-by-step explanation:

We have given that Drew has 4 pieces of rope 1 meter long each

He cuts the each rope into fifths means he will cut each rope in 5 parts

There is 4 rope

(a) So total number of fifth will be

(b) We have given that each rope is 1 meter long

So length of fifth part will be equal to

So total number of fifth will be 20 and each of length 20 cm

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

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
