Answer (x represents the first direction and the y represents the second direction):
- (x - 3) × (y + 5)
- New bedroom: 7 ft × 15 ft. Her new bedroom is 5 sq. ft larger than her old bedroom
I hope this helps!
I got it as 4 when calculating all have the same number which is 133
This conjecture is false, A and C don't have to be complementary angles.
Let Angle A be 100 and Angle B be 80 degrees. They are supplementary (sum of 180).
Let Angle C be 100 and Angle B is still 80 degrees. They are supplementary.
However, Angle A and Angle C are not complementary (sum of 90).

The 2nd choice is appropriate.
Example:
7x7x7x7x7x7x7x7x7x7x7x7=84
there are 12 sevens
u put the deleted number as the big number (7) and the number of repeated numbers as the smaller sized number which is called the exponent (12)
