Answer:

2.4

Step-by-step explanation:

3 / 28 = 0.12

0.12 x 20 = 2.4

(then we multiply how many miles he can run in 20 minutes)

Write the standard form of the equation of the circle with its center at (-5,0) and a radius of 8 what is the equation of the ci
Leto [7]

Answer:

\large\boxed{(x+5)^2+y^2=64}

Step-by-step explanation:

The standard form of an equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (-5, 0) and the radius r = 8. Substitute:

(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64

Easy + brainliest<br><br> 2x(^3) + 10x(^2) − 4x(^2)y − 20xy<br><br> factor this pls, (show all work)
Dimas [21]

Answer:

Answer:

2x • (x2 - 2xy + 5x - 10y)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

(((2•(x3))+(10•(x2)))-(22x2•y))-20xy

Step  2  :

Equation at the end of step  2  :

(((2 • (x3)) +  (2•5x2)) -  22x2y) -  20xy

Step  3  :

Equation at the end of step  3  :

((2x3 +  (2•5x2)) -  22x2y) -  20xy

Step  4  :

Step  5  :

Pulling out like terms :

5.1     Pull out like factors :

 2x3 - 4x2y + 10x2 - 20xy  =

2x • (x2 - 2xy + 5x - 10y)

Final result :

2x • (x2 - 2xy + 5x - 10y)
