Find X in the given figures

x = 4

Step-by-step explanation:

Given a tangent and a secant from an external point to a circle.

Then the square of the tangent is equal to the product of the secant's external part and the entire secant , that is

x² = 4(4 + 8) = 4 × 12 = 48 ( take square root of both sides )

x = = = 4

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
