Answer:
= 8.9 units
Step-by-step explanation:
When a chord intersects with a tangent outside a circle then we use the relationship;
X ² = AO × BO, Where A and are the points of intersection of the chord an the circle, while O is the point of intersection between the chord and the tangent.
Therefore;
x² = 4 × 20 or 8 × 10
x² = 80
x = √80
= 8.944
≈ 8.9
The expression for the above statement = (7x + 5)/(- 2x + 11)
The correct option is C.

What is algebra?</h3>
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout nearly all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
<h3>According to the given information:</h3>
let a number be x
Consequently, the result of seven times a number plus five is
7x + 5
Moreover, add the negative sums of two times the number and eleven.
- 2x + 11
Now, you can write the sentence "the total of seven times a number and five, divided by the sum of negative two times the number and eleven" as
(7x + 5)/(- 2x + 11)
The expression for the above statement = (7x + 5)/(- 2x + 11)

I understand that the question you are looking for is :
Write the expression "the sum of seven times a number and five, divided by the sum of negative two times the number and eleven" using algebra. choose the correct phrase below.
A. (–2x + 11) ÷ (7x + 5)
B. (–2x + 11) (7x + 5)
C. (7x + 5) (–2x + 11)
D. (7x + 5) ÷ (–2x + 11)
Divide the distance by the speed. Therefore the answer is 6 hours.

the larger rectangle
substitute
Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
