positive number times negative number is negative number "(+)(-) = (-)".
we change the mixed numbers to the improper fractions
The answer 73 because you is supposed to use your order of operations so in other words your supposed to use PEMDAS
The total lateral surface area
This is the area of the sides of the figure. In this case it will be the sum of the three rectangles.
(13) * (14) + (13) * (14) + (14) * (10) = 504yd ^ 2
the total surface area.
This is the surface area of the whole figure. In this case there are three rectangles and two triangles.
(13) * (14) + (13) * (14) + (14) * (10) + (1/2) * (10) * (12) + (1/2) * (10) * (12 ) = 624 yd ^ 2
the answer is
total lateral surface area: 504yd ^ 2
total surface area: 624 yd ^ 2
Answer:
maximum : 
a number infinitesimally larger than -29, or -28 if you prefer integers
minimum : 
negative infinity
Explanation:
if t + 31 < 2
than t + 31 - 31 < 2 - 31
t < -29
any number less than -29
ϵ just means infinitesimal small quantity denoted as
