Explain your answer (if u dont have time thats ok too)

The value of 2x + 2y, for x = 7 and y = 3, is 50.

So 2x + 2y = 50 when x = 7 and y = 3

2x + 2y = 50    Since x = 7, plug in 7 for "x". Since y = 3, plug in 3 for "y".

2(7) + 2(3) = 50

14 + 6 = 50

20 = 50

This is False because when x = 7 and y = 3, the value of 2x + 2y is 20, not 50.

The value of x²y², for x = 3 and y = 3, is 36.

So x²y² = 36 when x = 3 and y = 3

x²y² = 36   Plug in 3 for "x", and plug in 3 for "y"

(3)² · (3)² = 36

9 · 9 = 36

81 = 36

This is False because when x = 3 and y = 3, the value of x²y² is 81, not 36.
