If not, I am sorry.
If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.
Answer:
16 boxes in 10 minutes
Step-by-step explanation:
2/5 = 15 sec
15 ÷ 2=7.5 1/5 = 7.5 seconds
7.5 × 5 = 37.5 37.5 = 1 box

Answer:
12
Step-by-step explanation:
"ba" means "b * a", where * is multiplication. So, we want to find the product of a and b.
We know a = 3 and b = 4, so we just plug these in: 3 * 4 = 12.
Thus, ba = 12.

20x+5y=120
10x+7.5y=80 multiply this one by 2
___________
20x+5y=120
20x+15y=160 subtract
___________
-10y=-40 divide both sides by -10
____________
y=4
20x+5(4)=120 plug 4 in for y in the first equation
20x+20=120 multiply
20x=100 subtract
x=5 divide to find x
