Answer:

there is only one easy way to sole this

using quadratic equation

$\frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} \\ and \: \: \\ \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a}$

Step-by-step explanation:

a=6 b=5 c=-6

and by applying it to the equation you will get

x=0.66 and x=-1.5

Ryan and Sarah collect baseball cards. Ryan has 150 baseball cards and collects 10 cards per week. Sarah has 233 baseball cards

ICE Princess25 [194]

Answer:

About 17 weeks

Step-by-step explanation:

Given

Ryan:

$Initial = 150$

$Additional = 10$ (weekly)

Sarah:

$Initial = 233$

$Additional = 5$ (weekly)

Required

Determine the number of weeks they have the same cards

Represent the number of weeks with w:

For Both individuals, number of card at any given week is:

$Initial + Additional * w$

So,

For Ryan, the expression is:

$150 + 10 * w$

$150 + 10w$

For Sarah, the expression is:

$233 + 5 * w$

$233 + 5 w$

To determine the number of weeks, we have to equate both equations:

$150 + 10w= 233 + 5 w$

Collect Like Terms

$10w - 5w = 233 - 150$

$5w = 83$

Solve for w

$w = 83/5$

$w = 16.6$

16.6 implies about 17 weeks, because 16.6 approximates to 17

Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks

What is the length of the unknown leg in the right triangle?

Rama09 [41]

Answer:

we will use Pythagorean's Theorem

$25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15$

Therefore, the missing leg is 15 meters long.

Step-by-step explanation:

we will use pythagoras theorem

Given that,

One leg of the triangle is 20 meters long,

the hypothenuse is 25 meters long,

and the leg missing is called x.

we will use Pythagorean's Theorem

$25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15$

Therefore, the missing leg is 15 meters long.
