Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
Let Xavier's favourite fraction be a/b, Yessie's favourite fraction = b/a and Zorro's favourite fraction = c/d,
c/d x a/b = 12/35 . . . . . . . . (1)
c/d x b/a = 15/7 . . . . . . . . (2)
(1) x (2) = c/d x a/b x c/d x b/a = 12/35 x 15/7
c^2 / d^2 = 36/49
c^2 = 36
c = 6
d^2 = 49
d = 7
Xaviers favourite fraction = 12/35 / 6/7 = 2/5
Yessies favourite fraction = 5/2
Zorro favourite fraction = 6/7
Answer:
"More than" is the same as "greater than". The symbol for greater than is >
The inequality should be: c > 5

Answer:
√18, 13/3, 4.6, 4π
Step-by-step explanation:
joe = √18 = 4.24 mm
Lisa = 13/3 = 4.33 mm
Pablo = 4.6 = 4.60 mm
Julien = 4π = 12.56 mm
