The last one you’re correct , 16 is a perfect example of a perfect square
Answer:
The Radius is 7.5, the Diameter is 15, as you are just doubling the Radius
Step-by-step explanation:
Answer: Commutative Property
Step-by-step explanation: In Picture.
The value of y is 56 when x = 8.
Given
y = 343 when x = 49
Value of y varies directly with x
Therefore, y ∝ x
We can write the equation with a constant 'k'
y = kx
When y = 343 and x = 49
343 = k × 49
k = 343/49
k = 7
When x = 8,
y = kx
y = 7 × 8
y = 56
The value of y is 56 when x = 8.
