Answer:
9.784
Step-by-step explanation:
remember this formula for right triangles (a^2+b^2=c^2)
so 7.4^2+6.4^2=c^2
54.76+40.96=c^2
95.72=c^2
this is where we do this
square root of 95.72 is around 9.784
Answer:
Step-by-step explanation:
Answer:
(13 x + 6) (x - 2)
Step-by-step explanation:
Factor the following:
13 x^2 - 20 x - 12
Factor the quadratic 13 x^2 - 20 x - 12. The coefficient of x^2 is 13 and the constant term is -12. The product of 13 and -12 is -156. The factors of -156 which sum to -20 are 6 and -26. So 13 x^2 - 20 x - 12 = 13 x^2 - 26 x + 6 x - 12 = x (13 x + 6) - 2 (13 x + 6):
x (13 x + 6) - 2 (13 x + 6)
Factor 13 x + 6 from x (13 x + 6) - 2 (13 x + 6):
Answer: (13 x + 6) (x - 2)
<u></u>There are two way sof doing this question:
<em><u>1st solution is : </u></em>
<em> </em><u><em>6/15 = 2/</em></u><u /><em><u>5</u>
</em>because 6/15 is divisible by 3 and it is done by this form :
3 X 2 = 6
and
3 X 5 = 15
<em><u>2nd solution is:
</u></em><u></u>6/15 = 2/?
here we suppose that the missing value is <em>x:
</em> 6/15 = 2/x
you shift the denominators and then multiply them by the their numerators:
6 * x = 15 * 2
6x = 30
now you divide 6 on both sides:
<em> </em>6x/6 = 30/6
<em><u>x = 5</u></em><em>
