Which expressions show how 6 • 45 can be rewritten using the distributive property?A: 6×40+×5
B: 6×40-6×5
C: 6×50-6×5
D: 6×50+5

Answers

distributive property is
a(b+c)=ab+ac
a(b-c)=ab-ac

45=40+5 and 50-5 therfor

40+5=45
6*45=6(40+5)=6(40)+6(5) option A

also
50-5=45 so
6*45=6(50-5)=6(50)-6(5) option C


answer is A and C
Your answer is A because if you see,  (6x40) is equal to 240 and (6x5) is equal to 30 and if you add them you'll get 270 and (6x45) is equal to 270...

Nolan practices the piano for 1 2/5 hours every Saturday and Sunday. How long does he practice each weekend?

Answers

Well, you would have to convert them into improper fractions. So, 1 2/5 is 7/5. Then, you would do 7/5 x 2/1 which gives you 14/5 which equals 2 4/5. Nolan practices for 2 4/5 hours each weekend.

Answer:

y+20 = 9(x+2)

Step-by-step explanation:

The slope that passes through the points is

m = (y2-y1)/(x2-x1)

    = (79- -20)/ (9--2)

    = (79+20)/(9+2)

     = 99/11

     = 9

We can use point slope form to write an equation.  It says to use the first point.

y-y1 = m(x-x1)

y--20 = 9(x--2)

y+20 = 9(x+2)

Is a ice cube a polygon? why or why not?

Answers

No, because it is a cube shape and all shapes with four sides are polygons, and a ice cube is oblong /cuboid and it has 12 edges and 6 side.
hope I helped :)
also for more marks you could say that when ans ice cube melts it transfers into a different shape causing it to be a liquid, therefore if it was put in a polygon container, the water would be a ploygon
A Polygon is a two dimensional figure that can be  drawn on a flat surface.A cube is a three dimensional figure that can be sculpted in three dimensions but can only have projections of it drawn on a flat surface.So a cube is not a polygon.
