select the correct answer.\nwhat is the solution to the equation?\n$sqrt3{2x + 5}=5$\na. 240\nb. 65\nc. 60\nd. 5
Answer
Explanation:
Step1: Cube both sides of the equation
$(\sqrt[3]{2x + 5})^3=5^3$ $2x + 5=125$
Step2: Isolate the term with x
Subtract 5 from both sides: $2x=125 - 5$ $2x=120$
Step3: Solve for x
Divide both sides by 2: $x=\frac{120}{2}$ $x = 60$
Answer:
C. 60
