Step-by-step explanation:

The length of the wall will be 25 feet less than how long it was on day one.
You have to multiply both numbers. Since he can tear down 5 feet in one day, you would express that as 5x1. In 5 days, you would do 5x5 which gives you 25 feet. Hope this helped!
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
