Answer:
n < 2
Step-by-step explanation:
Let
The unknown number = n
8 < 4n
n < 8 / 4
n < 2
therefore, n must be less than 2
If n = 2
Then, 8 Will be equal to 4 times the number
Answer:
Step-by-step explanation:
17 11 9 and 7
Remember that the third side must be greater than 5 and less than 19.
Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y = when x = , then
= k( )² = k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k =
y = x² ← equation of proportion
When y = , then
= x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ± = ± 3
with positive value x = 3 → d
