Answer:
+73 yards.
Step-by-step explanation:
Since we have the first two quarters, we can simply work out the yardage for each game and add them together to get the total.
42-9 = 33 (first game)
58-18 = 40 (second game)
Therefore his total yardage was +73.
50 is not a perfect square because it doesn’t have a square root.
Hope this helped :)
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
