Answer:
I found the answer to this question by finding the square root of 49 because the section is a square. The square root of 49 is 7, so there are 7 tiles on each side of the floor.
Step-by-step explanation:
15.2
16 + 12 + 8 + 22 + 25 + 8 = 91 / 6 = 15.16 = 15.2
Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2
2x^2 + 3x - 20 = 0
(x + 4)(2x - 5) = 0
Solution:
x = -4
x = 5/2
No.
