Take the coefficient of x which is 20 and divide divide by two giving you 10 Now square that to get 100.
You would need to add 100 to both sides to complete the square.
This would basically be :
5 1/3 - 3 9/18
Then, make both fractions share a common denominator
5 6/18 - 3 9/18
Then, change the first number to make it compatible to subtract
4 24/18 - 3 9/18 = 1 15/18
Simplify
1 15/18 = 1 5/6
Answer:
A
Explanation:
Don’t quote me tho I’m not sure
Answer:
Yea sure its 102.5meters squared
The ratios 84/105 and 128/160 are proportional
<u>Solution:</u>
Given, two ratios are
and ![\frac{128}{160}](https://tex.z-dn.net/?f=%5Cfrac%7B128%7D%7B160%7D)
We have to give two different reasons to support the answer.
<em><u>Reason 1:</u></em>
Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.
![\text { Then, } \frac{84}{128}=0.65625 \text { and } \frac{105}{160}=0.65625](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Then%2C%20%7D%20%5Cfrac%7B84%7D%7B128%7D%3D0.65625%20%5Ctext%20%7B%20and%20%7D%20%5Cfrac%7B105%7D%7B160%7D%3D0.65625)
So numerators and denominators are in proportion, then given two fractions are proportion.
<em><u>Reason 2:</u></em>
Now, values of two fractions must be equal:
![\rightarrow \frac{84}{105}=\frac{128}{160} \rightarrow 84 \times 160=105 \times 128 \rightarrow 13440=13440](https://tex.z-dn.net/?f=%5Crightarrow%20%5Cfrac%7B84%7D%7B105%7D%3D%5Cfrac%7B128%7D%7B160%7D%20%5Crightarrow%2084%20%5Ctimes%20160%3D105%20%5Ctimes%20128%20%5Crightarrow%2013440%3D13440)
So, values of two fractions are equal, then they are in proportion.
Hence, the given two fractions are in proportion.
