What is 4(3+x) and how do I solve it

anastassius [24]

Answer:

12 + 4x

Step-by-step explanation:

To solve this you would have to use the distributive property.

The problem would basically go like this.

4 (3+x)

(Distribute)

(4x3) (4 x X)

4x3 = 12, 4 x x = 4x

So the answer would be 12 +4x

If 6/10 = 21/K what is K

timama [110]

You can cross multiply for this problem. So:

$\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35$

So K=35!

Select the correct answer.

Answer:

Option D is correct.

$Volume=\frac{8}{27}\ cubic\ yard$

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is $\frac{2}{3}\ yard$

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

$Volume\ of\ cone = (side)^{3}$

Now, we substitute value of length of stack in above equation.

$V=(\frac{2}{3})^{3}$

$V=\frac{2^{3}}{3^{3}}$

$V=\frac{8}{27}\ cubic\ yard$

Therefore, the volume of hay in each stack is $V=\frac{8}{27}\ cubic\ yard$
