Answer:

So the final answer is

$-8\sqrt{3}$

Step-by-step explanation:

Radicals:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.

The given expression is

$-5\sqrt{3} -3\sqrt{3}$

Now take common radical out so we will get

$\sqrt{3}(-5-3)$

Now add the Parenthesis part.

$\sqrt{3}(-8)$

So the final answer is

$-8\sqrt{3}$

Suppose the CPI has a value of 225.3 exactly one year ago, and the current value of this index is 231.16, a rise of 5.86 points.

sertanlavr [38]

Answer:

2.6%

Step-by-step explanation:

Given the current CPI = 231.56

Previous CPI (CPI a year ago) = 225.3

Rate of inflation over the past year = current CPI - previous CPI/previous CPI × 100%

Rate of inflation = 231.56-225.3/225.3 × 100%

5.86/225.3× 100%

= 2.6%

Rate of inflation over the past year will be 2.6%
