The sides of a square are 7 inches long. Enter the length of the diagonal of the square to the nearest tenth.

9.9 inches

Step-by-step explanation:

Use the pythagorean Theorem

c^2 = a^2 + b^2

c^2 = 7^2 + 7^2

c^2 = 49 + 49

c^2 = 98

Take the square root of both sides

c = 9.8994949366

Rounded

c = 9.9 inches

[ Answer ]

[ Explanation ]

3x - 7 = 4 + 6 + 4x

Solve Equation To Find Out How Many Solutions Are Possible:

Add Numbers: 4 + 6 = 10

3x -  7 = 4x + 10

Add 7 To Both Sides:

3x - 7 + 7 = 4x + 10 + 7

Simplify:

3x = 4x + 17

Subtract 4x From Both Sides:

3x - 4x = 4x + 17 - 4x

Simplify:

-x = 17

Divide Both Sides By -1:

=

Simplify:

X = -17

We Have One Solution, And One Solution Only. Therefore, There Is One Solution To The Equation.
