x + x + x + 2
There are 3 x's so that's
3x + 2
Yeah, you're right is D
2(x + 1) + x = 2x + 2 + x = 3x + 2
The other answer
Answer and step-by-step explanation:
Break the bracket out would be the first step to evaluate this expression:
3(x-1)
= 3x - 3
Hope this helped :3

A
Step-by-step explanation:
hope i helped you out :)
Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.
Angle I and Angle D are opposite angles. They add to 180 degrees
(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135
The measure of angle D is 135 degrees
