Area of square= 625 m sq Perimeter =??
sveticcg [70]

Answer:

<u>100 m</u>

Step-by-step explanation:

<u>Given</u> :

  • Area of square = 625 m²

<u>#1) Finding the side length</u>

  • Area = (side length)²
  • ⇒ side length = √Area
  • ⇒ side length = √625
  • ⇒ side length = 25 m

<u>#2) Calculating perimeter</u>

  • Perimeter = Total length of the sides of the shape
  • Perimeter = 4 x side length [a square has 4 equal sides]
  • ⇒ Perimeter = 4 x 25
  • ⇒ Perimeter = <u>100 m</u>

Sauron [17]

The function f(x) = 4(4)x represents the growth of a fly population every year in a remote swamp.

calculates three times a year, not just once a year.

f(x)= 4(4)^x

3 times a year

so x becomes 3x

f(x)= 4(1+r)^{3x}

4(4)^x=4(1+r)^{3x}

Take log on both sides

log(4)^x=log(1+r)^{3x}

log(4)^x=log(1+r)^{3x}

Use log property and move exponent before log

xlog(4)=3xlog(1+r)}

Divide both sides by x

log 4 = 3 log(1+r)

Solve for '1+r'

log 4 = log(1+r)^3

Remove log from both sides

4 = (1+r)^3

take cube root on both sides

1.584740= 1+r

1+r = 1.59

f(x)= 4(1+r)^{3x}

so equation becomes

f(x)= 4(1.59)^{3x}

1+r = 1.59

subtract 1 from both sides

So r= 59 = 59%

So growth factor is 59%

Answer is option C

An equation is shown below:
Naya [18.7K]

Answer:

The equation is 4(x-3) -(5x+1) = 3

The next step is solving the equation is to apply the distributive property and the equation becomes 4x - 12 - 5x - 5 = 3.

Hope I helped :D
