Answer:
$52.50
Step-by-step explanation:
25% = 0.25
All you have to do to find out the amount of the discount is multiply the original price by the sale percentage.
210 x 0.25 = 52.50
26.5 / 2 = a radius of 13.25. This * Pi = 41.605. The coin has a circumference of 41.605 mm.
(4x+7)(2x+5) Like this???
4x+7=2x+5 or like this?!!?!
<u><em>Answer:</em></u>
<u>The simplest form would be:</u>
8c² - 1.5d
<u><em>Explanation:</em></u>
To simplify an expression, we need to <u>gather the like terms</u>.
Like terms are the ones having the same variable raised to the same power
<u>In the given expression:</u>
6c² + 2.5d - d + 2c² - 3d
We have terms having c² and terms having d.
<u>Therefore, we would gather them as follows:</u>
6c² + 2.5d - d + 2c² - 3d
(6+2)c² + (2.5-1-3)d
8c² - 1.5d ......................> This is the simplest form
Hope this helps :)
