Which expression will you generate if you combine the like terms in 5x + 6x + y + y + 3y + 4 + 6 + 2?
a.
5(x + y + 7)
b.
5x + y + 2
c.
11x + 5y + 12
d.
x + 8y – 12
e.
2x + 4y – 10

C. 11x + 5y + 12. You add all the terms with x which would be 5x + 6x = 11x. Then you add (1)y+ (1)y + 3y = 5y. Last part should be easy, 4 + 6 + 2 = 12. Combine all of those and you have 11x + 5y + 12.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
