You have to combine like terms.
Like terms are those with the same letters raised to the same power.
These are the sums of the like terms:
1) 4y^2 + y^2 + 14y^2 = 19y^2
2) - 3y + 4y - 7y = - 6y
3) - 6 - 2 = - 8
Simplified expression: 19y^2 - 6y - 8<------------ answer
Answer:
The first one towards the left, or the green triangle, would be 70 degrees.
The second one, or the one in the middle, would be 108 degrees.
The last one, or the yellow triangle, would be 65 degrees.
Answer:
235
Step-by-step explanation:
183.3 ÷ 0.78 = 235
This is due to the rules of division.
Answer:
76 degrees
Step-by-step explanation:
this special line is an angle bisected.
that means it splits the angle at its starting point in 2 halves. as these names indicate, both parts are of equal size (half of the general angle).
we know one part (2) of this split angle : 38 degrees.
the other part (1) had to be equally sized : 38 degrees.
so, the total angle at point R is the sum of both split angles:
TRS = 38+38 = 76 degrees.
