Answer:
all of them except straight and reflex
Step-by-step explanation:
when angles are supplementary it means that they add up to 180
an acute angle is supplementary to an obtuse angle
an obtuse angle is supplementary to an acute angle
a right angle is supplementary to a right angle
but a reflex angle is over 180 so it's not supplementary to anything
and a straight angle is already 180 so it has no supplements either
Multiply both sides:
(2x + 2)(x + 3)
= 2x^2 + 6x + 2x + 6
= 2x^2 + 8x + 6
<h2>Answer: (1) 2x^2 + 8x + 6</h2>
