Fractional indices pls help
bulgar [2K]

Answer:

Formula used :

  • (a^m)^n = a^(m×n)
  • a^m × a^n = a^(m+n)

27 \times  {9}^{3x} =  {3}^{k} \\  {3}^{3}  \times   { {(3}^{2}) }^{3x}  =  {3}^{k}  \\  {3}^{k}  =  {3}^{3}  \times  {3}^{(2 \times 3x)}  \\  {3}^{k}  =  {3}^{3}  \times  {3}^{6x}  \\  {3}^{k}  =  {3}^{(6x + 3)}  \\  \boxed{k = 6x + 3}

  • <u>k = (6x+3)</u> is the right answer.

A rectangular room is 11 feet by 18 feet. The ceilings are 10 feet high. If a gallon of paint covers 250 square feet. How many g
Bingel [31]

Answer:

2.32 gallons of paint

Step-by-step explanation:

First, find the area of all 4 sides of the room, with the equation A = lw

11(10)

= 110 (for 2 of the walls)

18(10)

= 180 (for the other 2 walls)

Add these up:

110 + 110 + 180 + 180

= 580

Then, divide this by 250:

580/250

= 2.32

So, 2.32 gallons of paint will be needed to paint the room.
