Your friend has locked themselves out of the house, and they need your help to get back in. They have a 15 foot long ladder, and there is an open window 12 feet above the ground. How far from the of should you hold the ladder while they climb back in?

9 feet

Step-by-step explanation: A P E X

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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
