Answer:

$(2x-1)^2$

Step-by-step explanation:

$4x^2-4x+1=\\(2x)^2+2(2x)(-1)+(-1)^2\\\\\textrm{Using the rule }A^2+2AB+B^2=(A+B)^2\textrm{, then:}\\(2x)^2+2(2x)(-1)+(-1)^2=(2x-1)^2$

A baby was born 3/4 of a month early. At birth its weight was 7/8 kilograms, which is 9/10 kilograms less than the average weigh

BlackZzzverrR [31]

Answer:

The average weight of a newborn otter is 1.775 kg.

Step-by-step explanation:

We are given the following in the question:

Weight of newborn otter =

$\dfrac{7}{8}\text{ kg}$

Let x lg be the average weight of a newborn otter.

Thus, we are given the relation:

$\dfrac{7}{8} = x - \dfrac{9}{10}\\\\x = \dfrac{7}{8} + \dfrac{9}{10}\\\\x = \dfrac{35+36}{40} = \dfrac{71}{40}\\\\x = 1.775\text{ kg}$

Thus, the average weight of a newborn otter is 1.775 kg.

. How many strings are there of lowercase letters of length four or less, not counting the empty string

lesantik [10]

<h3>Answer: 475,254</h3>

This is one single number and not two separate numbers.

Delete the comma if your teacher requires it.

=========================================================

Explanation:

I'm assuming letters can repeat.

There are 26 letters in the English alphabet.

There are,

A = 26^4 = 456,976 strings of length four
B = 26^3 = 17,576 strings of length three
C = 26^2 = 676 strings of length two
D = 26 strings of length one

Overall, there are A+B+C+D = 456,976+17,576+676+26 = 475,254 strings of length four or less.

You originally draw a design for an art contest on a 4 in. x 5 in. card. The second phase of the contest requires the drawing to

Nutka1998 [239]

as we know that <span>If the 4" side of the card was scaled up to 10.5
then the scaling factor is 10.5/4 = 2.625.
The 5 side would be the length 5 x 2.625 = 13.125 which exceeds the maximum dimension of 11.

Thus, it is the 5 side which is scaled up to 10.5 and the scaling factor is therefore 10.5/5 = 2.1.
The scaled up length of the 4 side is thus 4 x 2.1 = 8.4.</span>
