Aballroom has a square dance floor. the area of the floor is 400 square feet. if the length of each side of the square increased by one foot, would its area be a rational number? choose each statement that is true about the new dance floor. a. the area of the floor would be a rational number. b. the area of the floor would be an irrational number. c. each side length would be a perfect square. d. the area of the floor would be a perfect square. e. the area of the floor would be a nonterminating, nonrepeating decimal.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

2

step-by-step explanation:

what am i looking for finish the question.

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
