Question

please tell me this answer.​

Answer 1

we have given that x^2=8 and value of y = 8

therefore x=15and x^2 =225 and y=225

Answer 2

Answer:

450

Step-by-step explanation:

given that y varies directly with x²

this means when we equate it we get a proportionality constant k

for solving k we got a condition that y=8 when x=2

from this y=kx² => k=2

so when x=15 then y= 2*225 => y=450
