Answer:
x = 6
Step-by-step explanation:
<em>If </em><em>two secants</em><em> are drawn from</em><em> a point outside </em><em>the circle, then the </em><em>product</em><em> of the lengths of</em><em> one secant </em><em>and its</em><em> external segment</em><em> equals the </em><em>product </em><em>of the lengths of</em><em> the other secant </em><em>and its</em><em> external segment</em><em> </em>
Let us solve the question.
∵ There is a circle in the given figure
∵ There are two secants intersected at a point outside the circle
∵ The length of one of them = 8
∵ The length of its external segment = x
∵ The length of the other secant = 4 + 8 = 12
∵ The length of its external segment = 4
→ By using the rule above
∴ 8 × x = 12 × 4
∴ 8x = 48
→ Divide both sides by 8
∴ x = 6
Answer:
462 words
Step-by-step explanation:
Maxine types :
294 words ⇒ 7 minutes
Let the known number of words be x.
So,
294 words ⇒ 7 minutes
x words ⇒ 11 minutes
Therefore,
294 ⇒ 7
x ⇒ 11
Now use cross multiplication and find the value of x.
7x = 294 × 11
7x = 3234
Now divide both sides by 7.
x = 462 words.
Hope this helps you :-)

C = (10/2)^2 = 25 to make this the square (x +5)^2.
Answer:
X=22.5
Step-by-step explanation:
Y=kX
20=15k
k=4/3
For X when Y=30
30=4/3×X
Cross multiply
4X=90
X=22.5
I think it is called the multiplier.
