Answer:
240
Step-by-step explanation:
We are given a right triangle. Based on the leg rule, the following equation shows how the length of a leg in a right triangle relates with the segments connected to the hypotenuse:
Hypotenuse/leg = leg/part
Where,
Hypo = 400
Leg = x
Part = 144
Substitute
400/x = x/144
Cross multiply
400*144 = x*x
57,600 = x²
√57,600 = x
240 = x
x = 240
Answer:
No polynomials are in standered form.
Step-by-step explanation:
Given polynmials are,



To find the polynomial of two variable in standered form we have to write the sum of the degree of each exponent in descending or ascending order.
(1) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending order or ascending so it is not a standered form.
(2) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending or ascending order so it is not a standered form.
(3) 
where sum of degree of exponents are of the form,
Sum of (degree of x+ degree of y)=
which is not a descending or ascending order so it is not a standered form.
