What is the degree of the following polynomial f(x)=(x+4)^3(x+1)(x-5)^3

x^7

Step-by-step explanation:

look for the highest degree of any term and you will end up multiplying

x^3( from first paranthesis)  *x( from second parenthesis) *x^3 ( from third paranthesis) so the highest degree will be x^ 3+1+3 = x^7

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

the answer is 13 cm
