Answer:
1.) adding by 0.3, 2.) adding by 0.8, 3.) adding by 1.1
Notice that
(1 - <em>x</em>)⁵ (1 + 1/<em>x</em>)⁵ = ((1 - <em>x</em>) (1 + 1/<em>x</em>))⁵ = (1 - <em>x</em> + 1/<em>x</em> - 1)⁵ = (1/<em>x</em> - <em>x</em>)⁵
Recall the binomial theorem:
Let <em>a</em> = 1/<em>x</em>, <em>b</em> = -<em>x</em>, and <em>n</em> = 5. Then
We get an <em>x</em> ³ term for
2<em>k</em> - 5 = 3 ==> 2<em>k</em> = 8 ==> <em>k</em> = 4
so that the coefficient would be
Answer E: 7
Answer D: 4.3
Explanation:
To find the length just divide 10 1/2ft by 1 1/2ft. To find the width divide 6 1/2ft by 1 1/2ft
16/40 , 12/30, 8/20 are all equivalent fractions and there are much, much more.
Answer:
The answer is 24/<u>2</u>=<u>36</u>/3=<u>66</u>/5.5=108/<u>9</u>=<u>180</u>/15.
Step-by-step explanation:
Given:
24/2=_/3=_/5.5=108/_=_/15.
Now, we need to solve this by putting in the place of _ and then continue:
<em>By</em><u><em> cross multiplication we get:</em></u>
By dividing with 2 we get:
Now, <u><em>we will continue like this process:</em></u>
And, then again:
And, last:
Therefore, the answer is 24/<u>2</u>=<u>36</u>/3=<u>66</u>/5.5=108/<u>9</u>=<u>180</u>/15.
