How do you solve #7sqrt(x+5)+10=66#?

Answer 1

Nathan Axel

x = 59

#7 sqrt(x + 5) + 10 = 66# #7 sqrt(x + 5) = 66 - 10# #sqrt(x + 5) = 56/7# #x+5 = 8^2# #x = 64-5# #x= 59#

To solve the equation 7√(x+5) + 10 = 66, you can follow these steps:

Start by subtracting 10 from both sides of the equation: 7√(x+5) = 56.
Divide both sides of the equation by 7: √(x+5) = 8.
Square both sides of the equation to eliminate the square root: (√(x+5))^2 = 8^2.
Simplify the equation: x + 5 = 64.
Subtract 5 from both sides of the equation: x = 59.

Therefore, the solution to the equation is x = 59.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
