Louis wants to carpet the rectangular floor of his basement. the basement has an area of 864 square feet. the width of the basement is 2/3 it's length. what is the length of louis's basement

36 or sqrt(1296)

Step-by-step explanation:

l * w = a(864)

We can substitute w in this equation for 2/3 * l.

l * (2/3 * l) = 864 or 2/3 * l ^2

Multiply by the denominator 3...

and then divide by what's left of the fraction 2

(864)*3/2 = 1296

1296 = l^2

This can also be seen as:

sqrt(1296) = l

36 = l

i will u if u answer my question in math

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
