Answer:
it can be simplified
Ans:6x squared +9x-5
Step-by-step explanation:
8x squared minus negative 2x squared is equal to positive six squared, +9x cannot be simplified because there are no other liked terms and -5 too.
Answer:
C. 18x + 9y: Because there isn't an relation between the two, all the others have and inequality sign meaning you can solve them, however C does not.
Step-by-step explanation:
So you find out how many triangles are in this by taking a point and making a line to another point that isn't on the same line. this one has 3 triangles. each triangle is 180*(using multiplication symbol for degree symbol).you do this to find out what the number of angles adds up to. 180* multiplied by 3 equals 540*. Then if you add up all the angles you have 400*. 540 - 400 equals 140*. So the final angle is 140*. Hope this helps!
