Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
THE SECOND ONE IS THE CORRECT ANSWER (B)

Answer:
The integers are 2,3,4
Step-by-step explanation:
Let one integer be = 
Since, the integers are consecutive, so they will increase by one.
So, 2nd integer will be =
3rd integer will be =
It is given that the 3 integers add up to 9.
So, we have the sum equation as:

Solving for 
Combining like terms.

Subtracting both sides by 3.


Dividing both sides by 3.


∴ 1st integer = 
2nd integer = 
3rd integer =
