Kelsey measured the sides of a porch to determine if it is a right triangle. does her porch with side lengths of 42 feet, 56 feet, and 70 feet form a right triangle?

yes, because 1st picture
yes, because 2nd picture
no, because 3rd picture
no, because 4th picture

Yes, because 2nd picture

Step-by-step explanation:

we know that

If the side lengths of a triangle satisfy the Pythagoras Theorem, then is a right  triangle  

The Pythagoras Theorem states that

where

c is the greater side

a and b are the legs of triangle

we have

substitute

therefore

Is a right triangle

unless if u could do my questions, if not i wouldn't want to

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
