Answer:
False
Step-by-step explanation:
If this number is larger than 6, then its square is larger than 36.
If x > 6, then x² > 36
The number is not larger than 6.therefore Its square is not larger than 36.
x ≤ 6; therefore, x² ≤ 36
-7 is < 6; however -7² > 36 as -7² = 49
31 is 25x3+8x3=51 because you multiply each of the numbers for it to equal 51
Answer:
r = 7
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 49 ← is in this form
with r² = 49 ⇒ r = = 7

Answer:
7.8 / 27.7 = 8 / 28 = 3.5
Step-by-step explanation:
7.8 / 27.7 = 8 / 28 = 3.5
20.6 / 70.19 = 21 / 70.2 = 3.3
5.9 / 21.96 = 6 / 22 = 3.6
15.47 / 56.4 = 15.5 / 56.4 = 3.6
