Plz need this urgent like now 20 points gabriella plans to purchase six laying hens. her family will enjoy the fresh eggs for breakfast. gabriella wants to create a rectangular enclosure for her chickens. her dad gave her 90 feet of fencing. gabriella decided that two of the side lengths would be 15 feet long. what could be the length of the other two sides? let r represent the length of each of the other two sides.

which of the equations below best represents the situation?

question 3 options:

a.90 = 30r + 2

b.90 = 30 + 2r

c.30 + 1/2r = 90

d.30r + 1/2 = 90

b.

Step-by-step explanation:

We are given that

Gabriella's father gave her fencing of length =90 feet

Length of each side  of two equal side =15 feet

Let length of  each side of other two equal  sides=r

We have to find the equation which represents the best situation.

Perimeter of rectangle =

Perimeter of rectangular enclosure=length of fencing

Using the formula

Hence, the required equation which represents the situation best is given by

Option b is true.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

combine all like terms then its just a 2 step equation
