Answer:

20b^4 + 23b^3 + 21b^2 Answer D

Step-by-step explanation:

4b^2 X 5b^2 = 20b^4

4b^2 X -3b = -12b^3

7b X 5b^2 = 35b^3

7b X -3b = -21b^2



35b^3 + (-12b^3) = 23b^3


20b^4 + 23b^3 -21b^2

You have a land-line telephone that costs $25.95/month plus a utilities tax of 4.5%. How much will you pay for your telephone us
dalvyx [7]

Answer

C) 325.41

Step by step explanation

The land-line telephone costs =$25.95

Utilities tax percentage = 4.5% = 4.5/100 = 0.045

Utility tax for amount $25.95 = 25.95*0.045

Utility tax = $1.17

The amount of telephone bill with tax = $25.95 + $1.17

= $27.12

There are 12 months in a year.

Telephone bill for a year = $27.12 * 12

= $325.44

Therefore, the nearest amount $325.41

You need to pay $325.41 as telephone bill for a year.

Thank you.

Solve the equation<br> 7+3m=28<br> A)m=18<br> B)m=11 2/3<br> C)m=9<br> D)m=7
Shtirlitz [24]
Firstly, you would subtract 7 from both sides, leaving you with 3m=21. You would then divide by three in order to be left with total value of m. 3m divided by 3 is m. 21 divided by 3 is 7. Therefore m=7 :)
