Answer:

Step-by-step explanation:

Area = L x W      gym area is (5x + 5x) ft²      if   W = 5x      Find the L

Area = L x W       divide both sides by W

Area/W  = (L x W) / W

Area/W  =  L  =  Area/W

    L = Area/W

       =  (5x + 5x) / (5x)

       =  5x( 1 + 1) / 5x

       =  5x(2) / 5x                      the 5x's cancel each other  5x/5x = 1

       =   2 ft          I got 2.  I suspect the 12 was a typo and should have been 2

What are the potential solutions to the equation 2ln(x+3)=0
skad [1K]
2\ln(x+3)=0\implies \ln(x+3)^2=0\implies e^{\ln(x+3)^2}=e^0\implies (x+3)^2=1

Expanding the left side gives

x^2+6x+9=1\implies x^2+6x+8=0\implies (x+4)(x+2)=0

which gives two solutions, x=-4 and x=-2. But if x=-4, then \ln(x+3)=\ln(-1), but this number isn't real, so x=-4 is an extraneous solution. Meanwhile if x=-2, you get \ln(-2+3)=\ln1=0, so this solution is correct.

"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.

What is (-7/8)(-3/4) simplified
Snowcat [4.5K]

Answer:

<h2>21/32</h2>

Step-by-step explanation:

-7/8 × -3/4 = 21/32

-7 × -3   = 21  

-8 × -4   = 32

21/32

<u><em>IMPORTANT: This number is not negative, because a negative times a negative is a positive.</em></u>

By the way, if you didn't know how to arrive at the fraction here's how.

First, Address input parameters & values.

Input parameters & values: The decimal number = 0.65625. Then, write it as a fraction

0.65625/1

Multiply by 100000 both the numerator & denominator

(0.65625 x 100000)/(1 x 100000) = 65625/100000

65.625% = 65.625/100 or 65625/100000

Find LCM (Least Common Multiple) for 65625 & 100000.

3125 is the LCM for 65625 & 100000

Divide by 3125

65625/100000 = (65625 / 3125) / (100000 / 3125)

= 21/32

I'm always happy to help :)
