Answer: y = 6
Step-by-step explanation:
A square's area can be done by using s^2, where s is y in this case. Because there are 5 squares, the area of the figure is 5y^2. Because the area is also 180cm, 5y^2=180.
Then divide both sides of the equation by 5 to get y^2 = 36. Then square root both sides of the equation to get y = 6.

80 mph x 4 = 320 miles. so the first car went 320 miles
520 miles apart- 320 = 200 I subtracted the 320 miles so i can figure out how far the other car went.

Hello! Your answer would be -10 degrees.
The temperature starts out eight degrees below zero. 0 - 8 = -8. Therefore, it starts off at -8 degrees.
Then, it increases by 5 degrees. Therefore, add 5 to -8. -8 + 5 = -3. Therefore, the next day has a temperature of -3 degrees.
Finally, it decreases by 7 degrees. -3 - 7 = -10. This shows us our final result - -10 degrees.
Hope this helps!
