5 0

Answer:

3.4

Step-by-step explanation:

my number divided by 0.1 is 23 less then 57...

let n represent the number

n / 0.1 = 57 - 23

n / 0.1 = 34...multiply both sides by 0.1, cancelling it on the left side

n = 34 * 0.1

n = 3.4 <===

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.
