Bill=parts+labor
labor=31 times hours or h
parts=125
bill=311

311=125+31h
minus 125 both sides
186=31h
divide both sides by 31
6=h

6 hours

311-125= 186
186/ 31=6

Tanzania [10]

Answer:

Option 4 is correct.

Step-by-step explanation:

Given the following options

we have to choose the difference of cubes.

Option 1:

$9w^{33}-y^{12}$

$9(w^{11})^{3}-(y^4)^3$

which is not the difference of cubes

Option 2:

$18p^{15}-q^{21}$

$18(p^5)^3-(q^7)^3$

which is not the difference of cubes

Option 3:

$36a^{22}-b^{16}$

$(6a^{11})^2-(b^8)^2$

which is the difference of square

Option 4:

$64c^{15}-a^{27}$

$(4c^5)^3-(a^9)^3$

which is the difference of cubes.
