Answer 1

Answer:

Disproved

Step-by-step explanation:

We are given the formula and what both variables equal. So, we can solve to see if this is true.

x = 54 and y = 45

54 + 45 = 11(54 + 45)

99 = 11(99)

99 ≠ 1089

Since they don't equal the same, this disproves it.

Best of Luck!

Answer 2

Step-by-step explanation:

If we use this formula then

X is 54 y is 45

54 + 45 = 11(54 + 45)

99 = 11(99)

99 = 1089

= 1089 - 99

= 990
