We want to write

$\frac{\sqrt[]{5}+1}{2}$

as decimal, doing it on a calculator we have

$\frac{\sqrt[]{5}+1}{2}=1.61803398875$

But we only need three decimal places, then the result is

$\frac{\sqrt[]{5}+1}{2}=1.618$

The total length of three boards is 7/8 of a yard. The length of two of the boards are 1/4 of a yard and 3/16 of a yard. What is

grigory [225]

Answer:

7/16 of a yard

Step-by-step explanation:

Let's put the boards to the same denominator so it's easier.

Let's go with a denominator of 16

1/4= 4/16

7/8= 14/16

3/16 stays the same.

So, 4/16+3/16+x=14/16

7/16+x=14/16

x=7/16 of a yard, the length of the 3rd board.

Find the product. (n 7)2 n² 14n 14 2n² 14n 49 n² 14n 49.

Marianna [84]

The product of $\rm (n+7)^2$ is $\rm n^2+14n+49$ .

Given

The product of $\rm (n+7)^2$ .

<h3>What is multiplication?</h3>

Multiplication is the process of calculating the product of two or more numbers.

The multiplication of numbers say, ‘a’ and ‘b’, is stated as ‘a’ multiplied by ‘b’.

The product of $\rm (n+7)^2$ is given by;

$\rm =(n+7)^2\\\\=(n+7)\times (n+7)\\\\= n(n+7)+7(n+7)\\\\=n^2+7n+7n+49\\\\=n^2+14n+49$

Hence, the product of $\rm (n+7)^2$ is $\rm n^2+14n+49$ .
