Two rectangles are similar. The smaller rectangle has a bottom side length of 3
and the larger rectangle has the corresponding side length of 30. If the left side
length of the smaller rectangle is 7, what is the measure of the corresponding left side of
the larger rectangle?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

what level of math? also i don't need to be paid if i can you.
