I think it is -2, if that helps
Answer:
Step-by-step explanation:
Rational expressions are bascially an expression where one polynomial is divided by another. And a polynomial is a series of terms like ax^b added together, where the exponents, what I labeled as b, need to be positive integers.
Ratio and proportion
height:shadow=1.5:2
for the building, shadow=24
1.5:2=h:24
1.5/2=h/24
multiply both sides by 24
36/2=h
18=h
the building is 18 meters
The answer is " 768 square feet. ".
Total surface area of a triangular prism = width x height +(sum of sides + width) x length and here;
width = 10
height = 12
sides = 13
length = 18
= (10 x 12) + (13 + 13 + 10) x 18
= 120 + (36 x 18)
= 120 + 648
= 768 square feet.
