To solve the system of equations below, zach isolated x^2 in the first equation
and then substituted it into the second equation. what was the resulting
equation?

x² + y² = 25 => x² = 25 - y²

x²/16 - y²/9 = 1

x²/16 - (25 - y²)/9 = 1 (b)

how many players are there?

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
