9t = 27.99
5t = ?
Cross-multiply : 9t? = 139.95t
?=15.55
The answer would be -9 -15n because you would be adding one to the -10 to the one and -9 and plus -2 and plus negative for any equals 15n
The answer is $116.18. 135 is 116.2% of the previous year.

Answer:
Third answer (she is incorrect because she should have squared each leg length and then found the sum.)
Step-by-step explanation:
The pythagorean theorem states that a²+b²=c². This is not equivalent to (a+b)²=c² (due to FOIL expansion, this expands to a²+2ab+b²=c²).
This matches with the third answer, as she has to do a² and b≥ separately.
**This question involves expanding perfect squares, which you may wish to revise. I'm always happy to help!
