All you have to do is the distance divided by the speed, since they didn't mention acceleration, you do 160/30 = 5.33 repeating so just round it and go with B I guess. Hope it helps!

Is there a rate of acceleration? If not then by using the formula time = distance/speed you get 160/30. Which equals 5.333, so I would go with B.

The height of a right rectangular prism is 3 units greater than the length of the base. The edge length of the square base is x
jok3333 [9.3K]

Answer:

B. x^3 + 3x^2

Step-by-step explanation:

Volume of a rectangular prism=width * length * height

V=w*l*h

h=3 greater than the length of the base

h=x+3

Length of the base=x

Width=x

Substituting values into the formula

V=w*l*h

=(x)*(x)*(x+3)

Multiplying

=(x^2)(x+3)

=x^3 + 3x^2

Option B is the correct answer

Answer:

 a - b2

Step-by-step explanation:

STEP  1 :

Trying to factor as a Difference of Squares:

1.1      Factoring:  a-b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  a1   is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares

Final result :

 a - b2

Solve the system of linear equations by substitution x-y=-4 2x+y=4
mylen [45]

Answer:

Given:

x-y=-4

2x+y=4

Step-by-step explanation:

x-y=-4

2x+y=4

add both the equation, we get

⇒  x-y=-4

  2x+y=4

⇒3x=-4+4

⇒3x=0

⇒x=0

∴ to find the value of y, put the value of x in any one equation

⇒x-y=-4

⇒0-y=-4

⇒-y=-4

⇒y=4

∴ x=0, y=4
