I really need help with math

Step-by-step explanation:

Angles in a Circle

We need to recall some basic concepts.

An inscribed angle is the angle formed in the interior of a circle when two secant lines intersect.

An arc of a circle is a portion of the circumference of the circle.

Theorem: Inscribed angles subtended by the same arc are equal.

In the figure provided, the points BD form an angle of 34° and the arc BD.

Similarily, arc BD also has two secants BE and DE that form the angle BED.

Thus, applying the above theorem, angle BED and 34° are subtended by the same arc, and the measure of BED is also 34°

answer: it's upside down and i can't read it

step-by-step explanation:

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

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
