Answer:
360 degrees
Step-by-step explanation:
The sum of all exterior angles in any convex polygon is 360 degrees.
Answer = 121°
Parallelograms’ angles are all equal. So the two given are equal.
6x + 13 = 7x - 5
x = 18
Plug x back into one of the original angles
6(18) + 13 = 121
Now we know all the angles are 121°, so that’s the answer
Answer:
No they're not equivalent
Step-by-step explanation:
5(x - 9) + 2x -1 -5(9 - x) - 2x
5x - 45 + 2x - 1 5x - 45 - 2x
7x + 46 does not equal 3x - 45
Explaining isnt my specialty, sorry
Answer:
16. f(y-2) = 2(y-2)²-5
= 2(y²-4y+4)-5
= 2y²-8y+8-5
= 2y²-8y+3
17. f(a+h)-f(a) = 2(a+h)²-5-(2a²-5)
= 2(a²+2ah+h²)-5-2a²+5
= 2a²+4ah+h²-2a²
= h²+4ah
