Question

add 9 + 16 to simplify the left side of the equation.

the image shows a right triangle with legs 3 and 4, hypotenuse c. the equations are:
$a^2 + b^2 = c^2$
$3^2 + 4^2 = c^2$
$9 + 16 = c^2$
then a box is shown with the arrow indicating it equals $c^2$.

Explanation:

Step1: Calculate 9 + 16

To simplify the left - hand side of the equation \(9 + 16=c^{2}\), we perform the addition operation. \(9+16 = 25\).

Answer:

25
