Martin won first place in the 100-meter dash with a time of 14 23/100 seconds.Samuel came in second place with a time of 15 7/10

ohaa [14]

Answer: The answer is 47th of 100 of a second.

Step-by-step explanation: Given that in the 100-metre dash, Martin won first place by taking a time of

$M_t=14\dfrac{23}{100}=\dfrac{1423}{100}~\textup{seconds}.$

And, Samuel came second by taking time of

$S_t=15\dfrac{7}{10}=\dfrac{157}{10}~\textup{seconds}.$

The difference between the time of arrival of Martin and Samuel is given by

$t=S_t-M_t=\dfrac{157}{100}-\dfrac{1423}{100}=\dfrac{47}{100}.$

Thus, Martin beat Samuel by forty seven - hundredth of a second.

Answer:

$x = - 2$

$x = - 5$

Step-by-step explanation:

Give

$(x - 5)(x + 12)$

Apply FOIL Method

$x {}^{2} + 7x - 60 = - 70$

Add 70 on both sides

${x}^{2} + 7x + 10$

Factor

$(x + 2)(x + 5)$

So our roots are

x=-2

x=-5
