Which of these systems of equations has infinitely many solutions? Explain how you know.
a. y = 3x – 6
y = 3(x - 2)

b. y = 5x +10
y = -5x + 10

c. y = 6x +18
y = 6x - 18

d. y = 3x + 12
y = 3(x + 9)

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
