Answer: 7
Step-by-step explanation:
As tangents drawn from a common external point to a circle are congruent,
- 8x - 7 = 6x + 7
- 2x - 7 = 7 [subtract 2x from both sides]
- 2x = 14 [add 7 to both sides]
- x = 7 [divide both sides by 2]
Answer:
21.42857143 = n
Step-by-step explanation:
Is means equals and of means multiply
12 = 56% *n
Change the percent to a decimal
12 = .56*n
Divide by .56
12/.56 = .56n/.56
21.42857143 = n

Answer:
9
Step-by-step explanation:
<u>→You can use the Pythagorean Theorem to solve this, by plugging in the numbers, like so:</u>
<u />
<u>→Subtract </u>
<u> from both sides:</u>
<u>→Subtract 12x from both sides:</u>
<u />
<u>→Factor out x:</u>
<u />
<u>→Separate, set = to 0, and solve:</u>
<u />
→ <u>Add 12 to both sides:</u> 
→So we have 0 and 12, as our answers. However, we cannot have 0 as a side length, since this would not be possible.
→All we need to do is take 12, and plug it into the equation for the shortest leg.
=(x^8 - x + 7) + (9x^8 + 6)
Combine like terms
=(x^8+9x^8)-x+(7+6)
=10x^8-x+13
D) 10x^8-x+13 is the answer.
Hope this helps! :)
