Sea: P(x)=3x^(a+2)+23x^(a+9)-x^(a+5) un polinomio de grado 13, calcular el valor de “a” hel me

Look at the highest degree term in P(x), which is 23x ^(a + 9). If the degree of P(x) is 13, then a + 9 = 13, so a = 4.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

hope this .
