Plz plz plz plz plz plz help me ​

a)1

b)3

c)0

d)2

Step-by-step explanation:

to find the degree of the polynomial just look at the exponents. The highest exponent you see is the answer. For polynomials with variable but no exponents (like in a) the degree is technically 1 for that expression. if there is just a digit with no exponent (like in c) then the degree is 0

-5/3

step-by-step explanation:

when a line is perpendicular to another line, it's slope is the negative reciprocal of the original line. the slope of the line given is 3/5 so the slope of the line perpendicular to this one is -5/3 : )
