Solve for x a. b. will mark brainliest!

a) x = 7

b) x = 2

Step-by-step explanation:

* Lets revise some facts in the circle

- If two secant segments are drawn to a circle from a point outside the

 circle, the product of the length of one secant segment and its

 external part is equal to the product of the length of the other secant

 segment and its external part.

# Example:

- If AC is a secant intersects the circle at points A and and B

- If DC is another secant intersects the circle at points D and E

- The two secants intersect each other out the circle at point C

∴ AC × CB = DC × CE , where AC is the secant and CB is its external

  part and DC is the secant and CE is its external part

* Lets solve the problem

a) There are two secants intersect each other at point outside the circle

∵ The first secant is x + 5

∵ Its external part is 5

∵ the second secant is 4 + 6 = 10

∵ Its external part is 6

∴ (x + 5) × 5 = 10 × 6 ⇒ simplify

∴ 5x + 25 = 60 ⇒ subtract 25 from both sides

∴ 5x = 35 ⇒ divide both sides by 5

∴ x = 7

* x = 7

b) There are two secants intersect each other at point outside the circle

∵ The first secant is 5 + 3 = 8

∵ Its external part is 3

∵ the second secant is x + 4

∵ Its external part is 4

∴ 8 × 3 = (x + 4) × 4 ⇒ simplify

∴ 24 = 4x + 16 ⇒ subtract 16 from both sides

∴ 8 = 4x ⇒ divide both sides by 4

∴ 2 = x

* x = 2

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
