2. would be 7^11 because when you’re multiplying with exponents on the same base number you add them together.
3. would be 54^3 because they have the same exponent, so you just multiply the base numbers
4. is true because when you multiply exponents on the same base number you add them, and 5+4 and 4+5 are both 9 so the order doesn’t matter

1. 7^30 because 5*6 equals 30 and u keep the base
2. 54^3 you multiply the base and keep the exponent
3. Yes because the associative property of multiplication still applies to exponents

I need to make sure the first one is correct and the second question i need help with

stiks02 [169]

Answer:

First one: 9 units

Second one: |2.5|, |-3|, |3.3|, |-4|

Step-by-step explanation:

9 units not negative 9 since you are counting the distance, not to or from, and the second one is the absolute value with each one, to simplify:

|-3|=3

|2.5|=2.5

|-4|=4

|3.3|=3.3

so the answer to the second one is |2.5|, |-3|, |3.3|, |-4|

You are creating concrete planters for a

kolezko [41]

Answer:

2044 cubic inches

Step-by-step explanation:

The amount of concrete required is the larger volume MINUS the smaller volume.

Note: Volume of cube = s^3 where s is the side length

Larger Volume = s^3 = 15^3 = 3375

and

Smaller Volume = s^3 = 11^3 = 1331

Hence, amount of concrete needed to make 1 planter = 3375 - 1331 = 2044 cubic inches

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l

Oksi-84 [34.3K]

The first three steps for solving the quadratic equation by completing the square are as follows;

1. $\rm 9x^2 +54x = 7$

2. $\rm 9(x^2 + 6x) = 7$

3. $\rm 9(x^2 + 6x + 9) = 7 + 81$

Given

The quadratic equation given as 9x^2 + 54x = 7.

<h3>Quadratic equation;</h3>

The highest power of the degree is 2 is known as a quadratic equation.

To solve using the completing the square method.

The first three steps for solving the quadratic equation by completing the square are given below.

1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.

$\rm 9x^2 +54x = 7$

2. Make sure that the coefficient of the x^2 term is 1.

$\rm 9(x^2 + 6x) = 7$

3. Adding a term to both sides that will complete the square on the left side.

This is done by dividing the coefficient of the x term by 2 and squaring it.

The same amount should be added to the right side to balance the equation.

$\rm 9(x^2 + 6x + 9) = 7 + 81$
