If -2 is added to a number and the sum is doubled, the result is -15 less than the number.
VMariaS [17]

The required number is 19 given that -2 is added to a number, the sum is doubled and the result is -15 less than the number. This can be obtained by assuming the number as x, converting the given conditions to algebraic expression, forming algebraic equation and solving for x.

<h3>Find the required number:</h3>

Here in the question it is given that,

  • -2 is added to a number
  • The sum is doubled
  • The result is -15 less than the number

We have to find the required number.

Let the required number be x.

⇒ -2 is added to the number ⇒ -2 + x

⇒ the sum is doubled ⇒ 2(-2 + x)

⇒ the result is -15 less than the number ⇒ 2(-2 + x) = x -(-15)

2(-2 + x) = x + 15

⇒ - 4 + 2x = x + 15

⇒ x = 19

Hence the required number is 19 given that -2 is added to a number, the sum is doubled and the result is -15 less than the number.

This is part two go cheap the part one to understand
Sauron [17]

Answer:

8

24

3

yes

Step-by-step explanation:

the original area of the figure is  4 · 2 which equals 8.

Since the dilation that is needing to be done is by a scale factor of 3 then all we need to do is multiply the original area by 3, which gives us the new area 24.

So because the only transformation was a dilation that didn't significantly change the figure then we can say that both figures are similar.

Why is the square root of (-5)^2 25 but the square root of -5^2 is -25? ‍
ipn [44]

Step-by-step explanation:

<h2><em>So, we call 5 the “square root” of 25 and write √25=5 because 52=25 . ... Since (−5)2 also equals 25 it is also a “square root” of 25 , but we write −√25=−5 because it is not the principal square root. Not all whole numbers have a whole number square root. For instance √2=1.414213562…</em></h2>
