The distributive law is satisfied if the numbers 1,2, and 3 are used as multyplying factors.

<h3>What is the distributive law?</h3>

This is basic mathematical law that states:

  • A multiplied by (b+c) equals (a x b) + (a x c)

<h3>Is this law satisfied if there are three numbers involved?</h3>

The law is always satisfied if one of the numbers is 1. Here is an example

  • 2 x (1+2+3) = 2 x 6 = 12

or

  • (2x1) + (2x2) + (2x3)
  • 2+4+6 = 12

If k is parallel to l find the value of a and the value of b.
kipiarov [429]

Answer:

a = 30

b = 40

C

Step-by-step explanation:

This requires that you use a proportion.

a / (a + 15) = 40 / 60

The small triangle's sides are in proportion to the large triangles sides.

Reduce the right. Divide top and bottom by 20

a/(a + 15) = 40/20 // 60/20

a/(a + 15) = 2/3                    

Cross multiply

3a = 2(a + 15)            Remove the brackets on the right.

3a = 2a + 30

Subtract 2a from both sides

3a-2a = 30

a = 30

Find B

b is done exactly the same way.

b/(b+20) = 2/3

3b = 2b + 40

3b - 2b = 40

b = 40

Which expression is equivalent to -7(y-2)
soldi70 [24.7K]

Hello!

Distributive property: a(b+c)=ab+ac

a=-7, b=y, c=2

-7y-(-7)*2

Minus and plus sign.

-7y+7*2

Then multiply by the numbers.

7*2=14

\boxed{=-7y+14}

Hope this helps!

Thanks!

Have a great day!

the volume of a box is represented by the roduct (x^2+5x+6) times (x+4). Give the polynomial that represents the length of the b
dimaraw [331]

Answer:

Step-by-step explanation:

x²+5x+6=x²+3x+2x+6=x(x+3)+2(x+3)=(x+3)(x+2)

so Volume=(x+3)(x+2)(x+4)

V=lwh

one of the factors is the length.
