Answer:
[See Below]
Step-by-step explanation:
✦ Given that
solve for y:
✧ ![y=6(1)-4](https://tex.z-dn.net/?f=y%3D6%281%29-4)
○ ![6*1=6](https://tex.z-dn.net/?f=6%2A1%3D6)
○ ![6-4=2](https://tex.z-dn.net/?f=6-4%3D2)
So ![y=2](https://tex.z-dn.net/?f=y%3D2)
✦ Given that
solve for y:
✧ ![y=6(3)-4](https://tex.z-dn.net/?f=y%3D6%283%29-4)
○ ![6*3=18](https://tex.z-dn.net/?f=6%2A3%3D18)
○ ![18-4=14](https://tex.z-dn.net/?f=18-4%3D14)
So ![y=14](https://tex.z-dn.net/?f=y%3D14)
✦ Given that
solve for y:
✧ ![y=6(10)-4](https://tex.z-dn.net/?f=y%3D6%2810%29-4)
○ ![6*10=60](https://tex.z-dn.net/?f=6%2A10%3D60)
○ ![60-4=56](https://tex.z-dn.net/?f=60-4%3D56)
So ![y=56](https://tex.z-dn.net/?f=y%3D56)

x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5. 5x + 12y = 80 5(4) + 12(5)=80 20+60=80. That is all. I hope that doesn't sound confusing
Answer:
B
Step-by-step explanation:
Note that i² = - 1
Given
(4 - 2i)(1 + 7i) ← expand factors using FOIL
= 4 + 28i - 2i - 14i²
= 4 + 26i + 14
= 18 + 26i → B
