Will mark brainliest. only answer if you know it. random answers will be reported.

b = 17.55

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + b^2 = 18^2

16 + b^2 = 324

-16              -16

b^2 = 308

square root them

b = 17.55

let me know if it is correct!

Step-by-step explanation:

4^2 + h^2 = 18^2

16 +h^2 = 324

h^2 = 308

h = √308

h = 17.5499 ft

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

1. 3. can also be expressed as (22/7)
