Find the difference.

1 answer:

3 0

To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,

(9x² + 10x + 4) - (9x² + 5x - 1)

= 9x² + 10x + 4 - 9x² - 5x + 1.

= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.

= 0 + 5x + 5 Combine the like terms.

= 5x + 5.

So, first choice is correct.

Hope this helps you!

Kazeer [188]

Answer:

$7.7

Step-by-step explanation:

Hello, I can help you with this

you can solve this by using a simple rule of three.

Step 1

define

if the wholesale price for a shirt is $5.50,it is 100 percent

$5.50⇔100%

the new price(x) is 40% more than the original, it means 140%

x ⇔ 140%

the relation is

$\frac{5.5}{100}= \frac{x}{140}\\$

Step 2

solve for x(isolate x)

$\frac{5.5}{100}= \frac{x}{140}\\x=\frac{5.5*140}{100}\\x=7.7$

the price of the shirt in the department store is $7.7

Have a nice day.
