Simplify 3n-(n+4) I am having trouble with it

The answer is 2n - 4.
This is the answer because behind that minus sign is a one. If you distribute that -1 after you distribute the -1 you get 3n - n - 4. Then simplify that you get 2n - 4

Alrighty. We can simplify using properties. Do you know what these are? please get back to me.

(14-8) × (15-4) <br> Use the order of operations to find the value of each expression

Yuliya22 [10]

Answer:

Step-by-step explanation:

the order of operations is the acronym PEMDAS which stands for:

P: Parentheses

E: Exponents

M & D: Multiplication and Division

A & S: Addition and Subtraction

we do these in order, from left to right in the equation

for the equation (14 - 8) x (15 - 4), we would start with solving the parentheses

there are 2 sets of parentheses, so we will go from left to right in solving it:

(14 - 8) = 6

(15 - 4) = 11

we replace the values we have found from the parentheses into the equation

6 x 11

now we go through the list

we can already eliminate exponents because there are none in this equation

the next step is multiplication & division, in this equation there is only multiplication, so we multiply 6 x 11 which gives us the answer 66

there is nothing left for us to do at this point, so 66 is our final answer

How much larger is the bigger faction 3/8, 11/15

natima [27]

Step-by-step explanation:

3/8 and 11/15

LCM = 30

3/8x4 and 11/15x2

12/30 and 22/30

22/30-12/30

=10/30

The difference is 10/30

The larger sum is 11/15

1. a. A cube’s volume is 512 cubic units. What is the length of its edge?

Vanyuwa [196]

Answer:

a) The length of its edge is 8 units.

b) The volume of the sphere is approximately 268.083 cubic units.

c) The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.

Step-by-step explanation:

a) The volume of a cube ( $V_{c}$ ), measured in cubic units, is defined by the following expression:

$V_{c} = L^{3}$ (1)

Where $L$ is the side length of the cube, measured in units.

If we know that $V_{c} = 512\,u^{3}$ , then the length of its edge is:

$L = \sqrt[3]{V_{c}}$

$L = 8\,u$

The length of its edge is 8 units.

b) The volume of a sphere ( $V_{s}$ ), measured in cubic units, that fits snugly inside this cube is defined by:

$V_{s} = \frac{\pi}{6}\cdot L^{3}$ (2)

If we know that $L = 8\,u$ , then the volume of the sphere is:

$V_{s} \approx 268.083\,u^{3}$

The volume of the sphere is approximately 268.083 cubic units.

c) The fraction of the cube taken by the sphere is the ratio of the volume of the sphere to the volume of the cube. That is to say:

$r = \frac{V_{s}}{V_{c}}$

If we know that $V_{c} = 512\,u^{3}$ and $V_{s} \approx 268.083\,u^{3}$ , then the fraction of the cube that is taken up by the sphere is:

$r = 0.524$

The result in percentage form is calculated by multiplying the result above by 100.

$\% r = 52.4\,\%$

The fraction of the cube that is taken up by the sphere is 0.524, whose equivalent in percentage form is 52.4 %.
