Answer:
-11,3
Step-by-step explanation: using foil (x-2)(X+10)=x^2+8x-20
x^2+8x-20-13=13-13 X^2+8x-33=0 factoring you get (x+11)(x-3)=0 so x+11=0
x-3=0
x=-11,3

Circumference =

We know that the circumference in here is equal to 23000 miles.
23000 = pi x d
pi will be approximated to 3.14
23000 = 3.14d
divide both sides by 3.14 to get
about 7325 as the diameter
I am assuming 5/3 refers to 5/3rds of a full revolution.
radians is easier for now so I'll do that first. on full revolution = 2π radians, but you have 1 and 2/3rds revolutions, so that is 2π+2π*(2/3)=10π/3 radian turn
to convert from radians to degrees multiply the radians by 180/π, so (10π/3)*(180/π) => 600degrees
Final answer:
5/3 turn is 600 degrees and 10π/3 radians

Answer:9 ounces of flours
Step-by-step explanation:90:9 ratio or sugar to flour
17.
B
Apply distributive property 2(5 - 3x) multiply 2 * 5, and 2 * -3x, you will end up with 10 - 6x.
18.
C
5*2x = 10x
5*4y = 20
Have a great day, good luck!
