You are watching: Solve for x, given the equation square root of x plus 9 − 4 = 1.
Answer: x = 16. Rearrange the radical top top the left next of the equation: square root of x + 9 = 1 + 4Calculate the su
Rearrange the radical top top the left side of the equation:sqrtx + 9 = 1 + 4Calculate the amount or difference:sqrtx + 9 = 5Power top top both sides:(sqrtx + 9)^2 = 5^2Simplify the radical expression:x + 9 = 5^2Rearrange unknown terms to the left next of the equation:x = 5^2 - 9Calculate the power:x = 25 - 9Calculate the amount or difference:x = 16Substitute right into one of the equations:sqrt16 + 9 - 4 = 1Calculate the sum or difference:sqrt25 - 4 = 1Factor and also rewrite the radicand in exponential form:sqrt5^2 - 4 = 1Simplify the radical expression:5 - 4 = 1Calculate the sum or difference:1 = 1Combine the results:x = 16Answer: x = 16
