Answer:
The answer is row C
Step-by-step explanation:
6 - 3 = 3
5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles
10x^3(8x^3+3x)
([10x^3 x 8x^3]+ [10x^3 x 3x])
80x^6+ 30x^4
•this is as simplified as it gets; it isn’t possible to add or subtract numbers with different exponents.
