(2-7m^6)^2<br><br><br> i dont know this
Pavel [41]
(2-7m^6)^2

rearrange terms:

(2-7m^6)^2

(-7m^6 + 2)^2

expand the squares:

(-7m^6 + 2)^2

(-7m^6 + 2)(-7m^6 + 2)

distribute:

(-7m^6 + 2)(-7m^6 + 2)

-7(-7m^6 + 2) • m^6 + 2(-7m^6 + 2)

distribute:

-7(-7m^6 + 2) • m^6 + 2(-7m^6 + 2)

49m^12 - 14m^6 + 2(-7^6 +2)

distribute:

49m^12 - 14m^6 + 2(-7^6 +2)

49m^12 - 14m^6 - 14m^6 + 4

combine like terms:

49m^12 - 14m^6 - 14m^6 + 4

49m^12 - 28m^6 + 4

solution:

49m^12 - 28m^6 + 4

djverab [1.8K]

Answer:

Total = \$103.20

Step-by-step explanation:

Given

Amount =\$160

D_1 = 30\% --- first discount

D_2 = 10\% --- second discount

Sales\ Tax = 7.5\%

Required

Determine the amount paid

First, we add the total discount:

D = D_1  + D_2

D = 30\% + 10\%

D = 40\%

If she got a discount of 40%, then she paid 60% (i.e. 100% - 40%)

So:

Amount = 60\% * \$160

Amount = \$96

Calculate the sales tax

Sales\ Tax = 7.5\% * \$96

Sales\ Tax = \$7.2

Total = \$96 + \$7.2

Total = \$103.20
