Your answer would be 128!

(17/8, -1/8) or if you want it in decimals (2.125, -0.125)2x-6y=5 x+y=2 y=2-x2x-6(2-x)=52x-12+6=58x-12=58x=17x=17/8(17/8)+y=2 You plug in the x-value to find the y-value now y=2-17/8y=-1/8

The answer I believe would be "D", the full shape of the triangle should add up to a total of 360 degrees, so adding "123" and "41" comes out to "164" So then you would just see which of the options would add up to 360.

Answer:

$\boxed{B. \: 5 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 2}$

Step-by-step explanation:

$= > (2 {x}^{6} + 8 {x}^{2} - x + 1) + (3 {x}^{6} + 5 {x}^{5} + 1) \\ \\ = > 2 {x}^{6} + 8 {x}^{2} - x + 1 + 3 {x}^{6} + 5 {x}^{5} + 1 \\ \\ = > 2 {x}^{6} + 3 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 1 + 1 \\ \\ = > 5 {x}^{6} + 5 {x}^{5} + 8 {x}^{2} - x + 2$
