Answer:
The legs of a 45 45 90 triangle are congruent so if one leg is x we can write (using the Pythagorean Theorem):
x² + x² = 18²
2x² = 324
x² = 162
x = 9√2
I think it’s C because I did have this question but I’m not sure
Step-by-step explanation:

1. 49/56 2. 25/30 I really need help with my work to
First, it says to simplify the expression, so you should try that first.
Simplified Expressions:
8y^15 and 36y^7
Then compare on which simplified expression has the greater exponent
8y^15 and 36y^7
8y^15 has the greater exponent
8y^15 = (y^9)(2y^2)^3 (Or the first expression)
The exponents of expression #1 are greater than the exponents of expression #2
