Answer:
A and D represent linear functions
while excluding 0, the product and quotient is positive if operating between same sign, otherwise if we operating different sign will resulted negative.
Answer:
√841
Step-by-step explanation:
You would use pythagorean theorem to solve this problem:
a² + b² = c²
a = 20 b = 21
20² + 21² = 400 + 441 = 841
√841
Answer: The formula is (b1 + b2)h+PH
