Solve for x and explain?

Mathematics
1 answer:
zhannawk [14.2K]3 years ago
4 0

Answer:

x = 7

Step-by-step explanation:

When 2 secants are drawn from an external point to a circle.

The product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

5(5 + x) = 6(6 + 4) ← distribute and simplify both sides

25 + 5x = 6 × 10

25 + 5x = 60 ( subtract 25 from both sides )

5x = 35 ( divide both sides by 5 )

x = 7

nasty-shy [4]

Answer:

the answer is \sqrt{5\\} , and - \sqrt{5\\} which is C.

Step-by-step explanation:

well I got that answer by doing this

we have x^{2}= 5

For x^{2}= f (a) the solutions are x = \sqrt{f(a)\\} , - \sqrt{f(a)\\}

so in this case the solutions are \sqrt{5\\}, and - \sqrt{5\\}

Sove for y 3 y + 13 equals 5 y - 5
Papessa [141]
If you could send an image that is clearer I will be able to help you more, but for what we have: 3y+13=5y-5, the answer would be 2y=18 (after doing all your algebra). Then you would divide both sides by 2 and get y=9. After this you can plug in 9 for every y and find the angles/measures of all sides!
Hope this helped, and if you need any further assistance, please let me know!
