Total number = 30
1/5 of 30 = 1/5 x 30 = 6
The attached figures show the total number of filled
circles in five lines. Each line have “6” filled circles.
So 5 lines having 6 filled circles = 5 x 6 = 30
<span>Every line represents “1/5” of total amount “30”. Which
proved that 1/5 of 30 is equal to 6. </span>
Answer:
Smaller is 18 and larger be 30
Step-by-step explanation:
Answer:
11- 64 degrees
12- 66 degrees
13- 89 degrees
14- 99 degrees
Step-by-step explanation:
11. 100 + 130 + 66 = 296
360 - 296 = <u>64</u>
12. 103 + 133 + 58 = 294
360 - 294 = <u>66</u>
13. 154 + 88 + 29 = 271
360 - 271 = <u>89</u>
14. 101 + 92 + 68 = 261
360 - 261 = <u>99</u>
hope this helps :)
Step-by-step explanation:





<u>Let us assume that:</u>

<u>Therefore, the equation becomes:</u>






<u>Now substitute the value of u. We get:</u>


<u>Therefore:</u>


★ <u>Which is our required answer.</u>

(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² - b² = (a + b)(a - b)
(a + b)³ = a³ + 3ab(a + b) + b³
(a - b)³ = a³ - 3ab(a - b) - b³
a³ + b³ = (a + b)(a² - ab + b²)
a³ - b³ = (a - b)(a² + ab + b²)
(x + a)(x + b) = x² + (a + b)x + ab
(x + a)(x - b) = x² + (a - b)x - ab
(x - a)(x + b) = x² - (a - b)x - ab
(x - a)(x - b) = x² - (a + b)x + ab
