30 points ! suzanne wants to put a fence around her square garden. if the garden covers an area of 100 ft2, how many feet of fencing does she need?

Suzanne needs of fencing

Step-by-step explanation:

Step 1

we know that

The area of a square is equal to

where

b is the length side of the square

In this problem we have

substitute and solve for b

square root both sides

Step 2

Find the perimeter of the square garden

The perimeter of the square is equal to

we have

substitute

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
