You can take out 2x^3 from both terms making it
2x^3 (15+8x^2)
Answer is B
Answer:
X - Y = 11 -------1
2x + y = 19 --------2
<em><u>Solving</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>elimination</u></em><em><u> </u></em><em><u>method</u></em><em><u> </u></em>
Multiple equation 1 by 2
2( X - y )= 22
2x - 2y = 22
2x + y = 19
Y = 3
Putting value of y= 3 in equation 1
X - 3 = 11
X = 11 + 3
X = 14
<h3>Value of X = 14 and Y = 3 </h3>
To find a fraction equivalent to 3/7 you just multiply the numerator (top number of fraction) and the denominator (bottom number of fraction) by the same number (i.e. 2/2, 5/5, etc.)
3/7 * 2/2 = 6/14
3/7 * 3/3 = 9/21
3/7 * 4/4 = 12/28
3/7 * 5/5 = 15/35
3/7 * 6/6 = 18/42
3/7 * 7/7 = 21/49
3/7 * 8/8 = 24/56
3/7 * 9/9 = 27/63
3/7 * 10/10 = 30/70
All of those are equivalent to the fraction of 3/7.
I hope you got a good grade on your assignment!!! :D
