Answer:
x4−5x3−6x2+26x+20
Step-by-step explanation:
(x−5)(x3−6x−4)
=(x+−5)(x3+−6x+−4)
=(x)(x3)+(x)(−6x)+(x)(−4)+(−5)(x3)+(−5)(−6x)+(−5)(−4)
=x4−6x2−4x−5x3+30x+20
=x4−5x3−6x2+26x+20

Answer:
A=3, B =3, C = 3
Step-by-step explanation:
9/3 (the letters) = 3 Each
3 - 24 - 3 = -27
2a = 6
6 - 3 + 3 = 6
A, b, c, all equal 3.
Since there are

in a circle, and central

, you can see that the part "sliced out" by the central angle is

of the whole circle.
This means that the length of the intercepted arc

is

of the circumference of the circle. So,
Answer:
a) 7 weeks b) George's
Step-by-step explanation:
Sally's score can be modeled by 10x+850.
George's score can be modeled by 50x+570.
We can set them equal to each other to see when they intersect.
10x+850=50x+570
40x=280
x=7
If George overtakes her in the 7th week, of course he'll have the higher score in 12 weeks.
