Simplify the radical 7√7-2√28
Umnica [9.8K]

ANSWER

3 \sqrt{7}

EXPLANATION

The given radical is

7 \sqrt{7}  - 2 \sqrt{28}

Remove the perfect square from the second radical.

= 7 \sqrt{7}  - 2 \sqrt{4 \times 7}

= 7 \sqrt{7}  - 2 \sqrt{4}  \times  \sqrt{7}

= 7 \sqrt{7}  - 2  \times 2 \times  \sqrt{7}

= 7 \sqrt{7}  - 4 \sqrt{7}

Subtract the like radicals

= 3 \sqrt{7}

Hypotenuse of triangle with sides of 36 and 39
worty [1.4K]

Answer: The hypotenuse is 53 (approximately)

Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,

AC^2 = 36^2 + 39^2

AC^2 = 1296 + 1521

AC^2 = 2817

Add the square root sign to both sides of the equation

AC = 53.0754

Therefore the hypotenuse is approximately 53 units.
