Which one of the following formulas correctly expresses this statement: a quantity x is equal to the sum of the squares of a and b? a. x = √a + b b. x = √ab c. x = 2a + 2b d. x = a2 + b2

The correct option is D.

Step-by-step explanation:

We have to find the expresses this statement: A quantity x is equal to the sum of the squares of a and b.

The square of a can be written as a² and the square of b can be written as b².

The sum of squares of a and b can be written as

Since the quantity x is equal to the sum of the squares of a and b, therefore

Therefore option D is correct.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
