In the sequence 0, 1, 1, 3, 6, 9, 27, ..., the first term is 0. Subsequent terms are produced by alternately adding and multiply
salantis [7]

Answer:

645

Step-by-step explanation:

Let's first try and write our series up to 125 before we know the next number.

Well continue from the given series.

0, 1, 1, 3, 6, 9, 27

The next number= 27+4= 31 , then 31 *4 = 124

The next after 124 = 124+5= 129, then 129*5 = 645

So actually the question was supposed to be the term greater than 124 because 125 does not exist in the series.

The number is 645

Someone help me with 20 and 19 ASAP please and thank you!!
DanielleElmas [232]

19) No, 3 should multiply both x and 2. As they, (x+2) are both inside the parentheses. The correct answer should be 3x + 6.

20) No, when it comes to exponents and multiply, exponents is done first before multiply. Therefore, Brett should square 3 first before multiplying it by 2. the correct steps should be

2 * 3^2 + 5

= 2* 9 + 5

=18 + 5

=23

The perimeter of a rectangle must be less than 172 feet. If the length is known to be 53 feet, find the range of possible widths
dlinn [17]

The interval notation for width of rectangle will be: (1,33)

Step-by-step explanation:

Perimeter of rectangle < 172 feet

Length of rectangle = 53 feet

Width of rectangle = ? (range of values)

The formula used to find perimeter of rectangle is:

Perimeter=2l+2w

where l is length and w is width

In our case we will use: 2l+2w because perimeter should be less than 172

Putting values:

2l+2w

So, width should be less than 33

Since width should be positive and greater than 0

So, the interval notation for width of rectangle will be: (1,33)
