This would be the distributive property!!

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products

hope this helps!

What is the numerator of the simplified sum? StartFraction x Over x squared + 3 x + 2 EndFraction + StartFraction 3 Over x + 1 E
ozzi

Answer:

4x + 6

Step-by-step explanation:

Given

\frac{x}{x^2+3x+2} + \frac{3}{x+1}

Before we can add the fractions we require them to have a common denominator.

Factor the denominator of the first fraction

\frac{x}{(x+1)(x+2)} + \frac{3}{x+1}

Multiply the numerator / denominator of the second fraction by (x + 2)

= \frac{x}{(x+1)(x+2)} + \frac{3(x+2)}{(x+1)(x+2)} ← fractions now have a common denominator

Add the numerators leaving the denominators

= \frac{x+3(x+2)}{(x+1)(x+2)}

= \frac{x+3x+6}{(x+1)(x+2)}

= \frac{4x+6}{(x+1)(x+2)} ← simplified sum with numerator 4x + 6

The CPI basket price for two consecutive years of five different economies are given. Determine the rate of Inflation for each e
kaheart [24]

Answer:

The inglation rate can be calculated as:

R = ((year2 - year1)/year1 )*100%

A)

Year 1 = $132.00

Year 2 = $134.50

R = (($134.50 - $132.00)/$132.00)*100% = 1.89%

B)

Year 1 = $95.00

Year 2 = $97.50

R = (($97.50 - $95.00 )/$95.00 )*100% = 2.6%

C)

 Year 1 = $100.00

 Year 2 = $102.00

R = (($102.00 - $100.00 )/$100.00 )*100% = 2%

D)

Year 1 = $88.00

Year 2 = $89.25

R = (($89.25 - $88.00 )/$88.00 )*100% = 1.4%

E)

Year 1 = $115.50

Year 2 = $117.50

R = (($117.50 - $115.50 )/$115.50 )*100% = 1.7%

Then the order from least to greatest is:

D, E, A, C, B

Allen is showing his work in simplifying –8.3 + 9.2 – 4.4 + 3.7. Identify and explain any errors in his work or in his reasoning
skelet666 [1.2K]

Additive inverse; you can't just take -4.4 and make it positive.
