For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
I'd use synthetic div. here, with 2 as my divisor:
________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
2.77 × 10 ^ ( -3 ) is the answer
Answer:
-45
Step-by-step explanation:
put x = -6 and y=3 in this expression : y(2x - y)
3(2(-6)-3) = 3(-12 -3)= 3(-15) = -45
X+1+x+2+x+3+x+4+x+5+x+6+x+7+x+8+x+9+x+10+x+11+x+12/12
12x+78/12 = 132 times 12 is
12x+78 = 1,548 minus 78
12x = 1,506 divide by 12
x = 125.5 I believe is the answer, sorry if it is wrong
