Solve for x. round to the nearest tenth.

x ≈ 11.7

Step-by-step explanation:

When 2 secants are drawn from an external point to a circle then

The products of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant, that is

3(3 + x) = 4(4 + 7)

9 + 3x = 4 × 11 = 44 (subtract 9 from both sides )

3x = 35 ( divide both sides by 3 )

x ≈ 11.7

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
