Welcome to Brainly!

Binomial Theorem will follow this pattern:
The powers start at 3 and decrease down to 0 for the first term,
and start at 0 and increase to 3 for the other term.

(2x+4)^3 =

$\rm \_\_(2x)^34^0+\_\_(2x)^24^1+\_\_(2x)^14^2+\_\_(2x)^04^3$

See how the power counts down on the (2x)
and counts up on the 4?
That's the pattern that our expansion must follow.

I left a little space in front of each term.
The coefficient in front of each term will come from the fourth row of Pascal's Triangle. The one that looks like this:

1 3 3 1

Those are the coefficients we want:

$\rm 1(2x)^34^0+3(2x)^24^1+3(2x)^14^2+1(2x)^04^3$

We can clean this up a little bit by getting rid of some of the junk. Anything to the 0th power is 1. So let's suppress all of our 1's because multiplying by 1 is not important.

$\rm (2x)^3+3(2x)^24+3(2x)4^2+4^3$

Now apply exponent rule, distributing the power to both the 2 and the x where applicable.

$\rm 2^3x^3+3\cdot2^2x^24+3\cdot2x4^2+4^3$

Remember, multiplication is COMMUTATIVE, meaning we can multiply things in any order. So let's bring the numerical portion to the front of each term and multiply it all out.

$\rm 2^3x^3+3\cdot2^2\cdot4x^2+3\cdot2\cdot4^2x+4^3$
$\rm 8x^3+48x^2+96x+64$

Choose the answer. 4. (1 pt) Which property justifies this statement? If x + y = z and z = x + 4, then x + y = x + 4. A. symmetr

The symmetric property of equality says that if a = b, then b = a.

The associative property for addition merely states that a+(b+c) = (a+b)+c.

The distributive property says that if a, b, and c are real numbers, then

a · (b + c) = (a · b) + (a · c).

The transitive property of equality says that if a = b and b = c, then a = c.

Consider statament: If x + y = z and z = x + 4, then x + y = x + 4. Denote a=x+y, b=z and c=x+4. Now you have if a=b and b=c, then a=c. This is exactly transitive property.

Marnie pays $.06 per kilowatt-hour for electricity. She has budgeted $72 for her electricity. What is the greatest number of kil

Bond [772]

Answer:

1200 kilowatt-hours

Step-by-step explanation:

You want to divide 72 by .06 to get how many times .06 can go into 72. that answer is how many hours Marnie can use with $72, 1,200.
