Answer:

Step-by-step explanation:
We are given:

And we want to solve for <em>x</em>.
First, we can add 49 to both sides:

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

Evaluate:

Subtract 7 from both sides:

So, we have two solutions:

Evaluate:

So, from least to greatest, our solutions are:

Step-by-step explanation:
The answer is 30 ft²
The surface area (SA) of a pyramid is the sum of lateral area (LA) of the pyramid and the area of its base (BA):
SA = LA + BA
The area of the pyramid base (which is a square) with base edge a is:
BA = a²
We have:
SA = 55 ft²
LA = ?
a = 5 ft
LA = SA - BA = SA - a²
LA = 55 - 5²
LA = 55 - 25
LA = 30 ft²
