Find the equation of a polynomial function with integer coefficients that has the following rootsb. 4, 5-2i

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

15m is what percent of 60m; 3m; 30m; 1.5 km? the last one is km not m

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
